U.S. Citizenship and Immigration Services (USCIS) — the agency within the Department of Homeland Security that adjudicates most immigration benefits — is one of the most consequential federal agencies in any immigrant’s life, and one of the most opaque to navigate. Its website holds answers to most procedural questions, but those answers are scattered across hundreds of pages, dozens of forms, and shifting policy guidance. For someone trying to file a green card application, check a case status, schedule an appointment, or simply understand where their case stands, the USCIS ecosystem can feel impenetrable.
This guide is a practitioner’s reference to navigating USCIS effectively. It covers the official tools every applicant should know about — the myUSCIS online account, the case status checker, the processing times tool, the InfoPass appointment system, the contact center, and the FOIA request process — alongside the forms and fees you are likely to encounter, the role of related agencies like the National Visa Center and the Executive Office for Immigration Review, and where attorney guidance becomes valuable. The post is written by a New York immigration attorney whose practice routinely interfaces with the USCIS New York field office at 26 Federal Plaza and field offices nationally.
Understanding the USCIS Ecosystem
USCIS is one of several federal agencies that touch immigration matters. Understanding which agency does what — and how to reach each one — saves enormous time and frustration.
USCIS and Its Place in the Federal System
USCIS is part of the Department of Homeland Security (DHS), created in 2003 when the legacy Immigration and Naturalization Service was reorganized into three separate agencies. USCIS handles affirmative benefits: green cards, naturalization, work authorization, family petitions, asylum applications filed affirmatively, and most nonimmigrant change-of-status applications. The agency’s official overview details its organizational structure and mission.
USCIS does not handle removal or deportation proceedings — those fall under the Executive Office for Immigration Review (EOIR), which operates within the Department of Justice. Interior enforcement is the domain of Immigration and Customs Enforcement (ICE), border enforcement belongs to Customs and Border Protection (CBP), and visa issuance abroad is handled by the Department of State through its consular posts. This division matters because contacting the wrong agency about an immigration issue produces no result. Identifying which agency controls your matter is always the first step.
Other Agencies You May Encounter
Department of State / Consular Posts — The State Department issues visas at U.S. embassies and consulates abroad. Applicants undergoing consular processing for an immigrant visa will interact with both the National Visa Center (NVC), which handles case preparation between USCIS approval and the consular interview, and the consular post itself for the interview and visa issuance. The Travel.State.Gov website is the primary resource for consular processing.
Executive Office for Immigration Review (EOIR) — The immigration courts under the Department of Justice adjudicate removal proceedings. The Board of Immigration Appeals (BIA) serves as the administrative appellate body within EOIR. Individuals in removal proceedings interact with EOIR, not USCIS, for their court matters — though some USCIS benefits can still be filed while proceedings are pending.
Customs and Border Protection (CBP) — CBP handles port-of-entry inspections, ESTA determinations, and advance parole admissions. Travelers entering the United States interact with CBP officers, not USCIS officers, at airports and land borders.
Immigration and Customs Enforcement (ICE) — ICE handles interior enforcement, detention, and removal operations. Individuals with ICE detainers, check-in appointments, or orders of supervision interact with ICE’s Enforcement and Removal Operations (ERO) division.
Department of Labor (DOL) — The DOL’s Employment and Training Administration administers the PERM labor certification process and prevailing wage determinations required for many employment-based green card categories. Employers filing for foreign workers encounter the DOL before reaching USCIS in the process.
When something has gone wrong with an immigration matter, identifying which agency is involved is the first step. The wrong contact channel produces no result; the right one usually produces an answer.
The myUSCIS Online Account: Why Every Applicant Should Have One
The single most useful USCIS tool — and the one most applicants underuse — is the free myUSCIS online account at my.uscis.gov.
A myUSCIS account allows applicants to file certain applications online, track USCIS case status across all pending cases in one place, view notices and approval documents, respond to requests for evidence (RFEs) electronically, view biometrics appointment letters, and message USCIS securely through the account portal. For applicants managing multiple pending cases — common when filing an I-485 concurrently with an I-765 and I-131 — the consolidated view alone justifies creating the account.
USCIS forms currently available for online filing through myUSCIS include the I-90 (green card replacement), I-130 (family petition), I-131A (travel document), I-765 (employment authorization), N-400 (naturalization), N-565, N-600, N-600K, AR-11 (change of address), I-589 (asylum), and I-907 (premium processing), among others. The list of forms available for online filing expands periodically — check uscis.gov for the current roster.
Creating an account is straightforward: visit my.uscis.gov, register with an email address, verify your identity, and set up two-factor authentication. For cases originally filed on paper, the “Access My Case” feature links a paper-filed case to your online account using the USCIS receipt number. If you have attorney representation, your attorney can file a Form G-28 (Notice of Entry of Appearance) and access your case through their own myUSCIS account.
Create a myUSCIS account even if you do not currently have a pending case. Having the account set up before you file means you can immediately link the case to your account once a receipt number issues. This dramatically reduces the friction of receiving notices, responding to RFEs, and tracking the case’s progress.
How to Check USCIS Case Status
Checking USCIS case status is the most common reason people visit the USCIS website. The system provides useful information, but understanding its limitations prevents unnecessary anxiety.
Using Your Receipt Number
Every USCIS case receives a receipt number on Form I-797C, Notice of Action, that begins with a three-letter prefix indicating the service center or office processing the case. Common prefixes include EAC (Vermont Service Center), WAC (California Service Center), LIN (Nebraska Service Center), SRC (Texas Service Center), MSC (Missouri Service Center / National Benefits Center), IOE (electronic filing), NBC (National Benefits Center), and YSC (Potomac Service Center). The receipt number is the key to checking case status online — without it, no online status check is possible.
The Case Status Online Tool
The public Case Status Online tool requires only your 13-character receipt number. After entering the number, the system displays the most recent status update for your case. Common status messages and their general meanings include:
- “Case Was Received” — USCIS has accepted the filing. No substantive review has occurred yet.
- “Case Was Updated To Show Fingerprints Were Taken” — Biometrics have been completed and recorded.
- “Case Is Ready To Be Scheduled For An Interview” — Pre-interview readiness. The actual interview notice will follow separately.
- “Interview Was Scheduled” — An interview date has been set. The notice with date, time, and location will arrive by mail and appear in your myUSCIS account.
- “Case Was Approved” — A favorable decision has been rendered.
- “Request for Initial Evidence Was Sent” / “Request for Evidence Was Sent” — An RFE has been issued. A response is required by the stated deadline, typically 87 days.
- “Case Was Denied” — A denial has been issued. Depending on the form type, a motion to reopen, motion to reconsider, or appeal may be available.
Case status updates are not always real-time. A case can be approved internally days before the online status reflects approval. Conversely, the online system sometimes shows “Case Was Updated” without any substantive change. Do not refresh the status page obsessively — it will not change adjudication speed.
Case Status Through Your myUSCIS Account
A myUSCIS account provides richer information than the public case status checker, including copies of notices, document upload capability, and message history with USCIS. For cases linked to the account, this is the primary and preferred method for monitoring case progress. If you have not yet created a myUSCIS account, the guidance above explains how to set one up and link existing cases.
USCIS Processing Times: How to Find Out How Long Your Case Will Take
“How long will my case take?” is the question immigration attorneys hear most often. USCIS provides a tool for this, but interpreting its output requires context.
The Official Processing Times Tool
USCIS publishes processing times at egov.uscis.gov/processing-times. The tool allows you to select a form type and a service center or field office, then displays the current processing time range. Processing times are stated in ranges (for example, “8 months to 17 months”) representing the time within which 80% and 93% of cases at that office completed in the prior reporting period. These ranges are updated monthly.
Processing times vary significantly by form, by service center, by field office, and over time. A marriage-based I-485 adjustment of status at the New York field office will have different processing times than the same form at the Los Angeles field office. An I-130 filed at the Texas Service Center may process faster or slower than one filed at the Nebraska Service Center depending on current workloads.
Why Processing Times Vary
Several factors contribute to the wide variation in USCIS processing times. Staffing levels and budget cycles directly affect throughput — USCIS is primarily fee-funded, so filing volume fluctuations create capacity mismatches. Backlog accumulation during pandemic-era office closures continues to affect many case types years later. Whether a case requires an interview, biometrics, or additional security checks affects timeline. Cases involving applicants from certain countries of origin may undergo extended FBI name checks or interagency background reviews. And the issuance of an RFE, Notice of Intent to Deny (NOID), or Notice of Intent to Terminate (NOIT) pauses adjudication until the applicant responds.
When You Can Make a Case Inquiry for Delayed Cases
USCIS allows case inquiries through the contact center or online service request when a case has exceeded the published processing time. The processing times page publishes a “case inquiry date” for each form and office — cases with receipt dates before that date are eligible for a service request. Applicants can submit a case service request online at egov.uscis.gov/e-request or by calling the USCIS Contact Center. Service requests are typically answered within 30 to 60 days. They do not generally speed up the underlying adjudication, but they sometimes surface issues like lost mail, stalled background checks, or cases that were inadvertently set aside.
USCIS Forms: A Reference Guide
USCIS administers more than 100 forms covering nearly every immigration benefit. Understanding which form is required, where it goes, what supporting documents accompany it, and what the current fee is can be the difference between an efficient filing and a months-long delay. The USCIS forms directory lists every current form with instructions.
Family-Based Forms
Form I-130 (Petition for Alien Relative) — Filed by U.S. citizens and lawful permanent residents to petition for qualifying relatives. The I-130 is the foundational petition for most family-based immigration and is a prerequisite for the relative’s eventual adjustment of status or consular processing. Verify the current fee at uscis.gov. For guidance on the I-130 process, see Yazdi Law’s I-130 petition page.
Form I-129F (Petition for Alien Fiancé) — Filed by U.S. citizens to petition for a foreign fiancé(e) under the K-1 visa program. The I-129F initiates a multi-agency process involving USCIS, the National Visa Center, and the U.S. consular post abroad. For a comprehensive walkthrough of the K-1 process, see our K-1 Fiancé Visa Complete Guide.
Form I-485 (Application to Adjust Status) — Filed by individuals inside the U.S. seeking to become lawful permanent residents. Commonly filed concurrently with an approved I-130 for immediate relatives of U.S. citizens, or based on an employment-based immigrant petition. Verify the current fee at uscis.gov. See marriage-based green card for more on the adjustment of status process.
Form I-751 (Petition to Remove Conditions on Residence) — Filed by conditional permanent residents — those who received their green card based on a marriage less than two years old at the time of approval — within the 90-day window before the conditional green card expires. Failure to file the I-751 timely can result in termination of permanent resident status. See removal of conditions for details on the joint filing and waiver options.
Form I-864 (Affidavit of Support) — Filed by petitioners and joint sponsors to demonstrate income sufficient to support the intending immigrant at 125% of the federal poverty guidelines. Required for most family-based and certain employment-based immigrant visa applications. No separate filing fee.
Employment-Based Forms
Form I-140 (Immigrant Petition for Alien Worker) — Filed by employers (or self-petitioners in EB-1A extraordinary ability and EB-2 National Interest Waiver cases) to establish eligibility for employment-based immigrant categories. Verify the current fee at uscis.gov.
Form I-129 (Petition for a Nonimmigrant Worker) — Filed by employers for H-1B, L-1, O-1, TN, and other nonimmigrant work categories. Verify the current fee at uscis.gov.
Form I-907 (Request for Premium Processing) — Optional, fee-based premium processing for eligible forms, typically guaranteeing adjudication or issuance of an RFE or NOID within 15 business days for most eligible categories. Premium processing is available for select I-140 and I-129 categories and has expanded to certain I-539 and I-765 categories in recent years. Verify current eligibility and fee at uscis.gov.
Work Authorization and Travel Forms
Form I-765 (Application for Employment Authorization) — Filed by various categories of noncitizens to request work authorization (EAD). Often filed concurrently with Form I-485 during adjustment of status. Also filed by asylum applicants, TPS and DACA recipients, and certain other categories. Verify the current fee at uscis.gov.
Form I-131 (Application for Travel Document) — Filed to request Advance Parole (for adjustment of status applicants traveling abroad while their case is pending), Reentry Permits (for LPRs anticipating long absences from the U.S.), and Refugee Travel Documents. Verify the current fee at uscis.gov.
Naturalization and Citizenship
Form N-400 (Application for Naturalization) — Filed by lawful permanent residents seeking to become U.S. citizens after meeting the continuous residency, physical presence, and good moral character requirements. The naturalization process involves a biometrics appointment, an interview with a USCIS officer, an English and civics test, and an oath ceremony. Verify the current fee at uscis.gov. See naturalization and citizenship for details on eligibility.
Form N-600 (Application for Certificate of Citizenship) — Filed by individuals who are already U.S. citizens through derivation (a parent who naturalized while the child was under 18 and an LPR) or acquisition (born abroad to a U.S. citizen parent) to obtain documentary proof of citizenship. Verify the current fee at uscis.gov.
Other Common Forms
Form G-28 (Notice of Entry of Appearance as Attorney) — Filed by attorneys entering an appearance to represent an applicant before USCIS. Required for USCIS to communicate directly with the attorney and for attorney access to the case through myUSCIS. No filing fee.
Form AR-11 (Alien’s Change of Address) — Required of all noncitizens who change their U.S. address. Must be filed within 10 days of moving, per INA § 265. Often missed by applicants — failure to file can have serious consequences in removal proceedings and may affect pending applications if USCIS sends notices to an outdated address. Can be filed online through myUSCIS at no cost.
Form I-90 (Application to Replace Permanent Resident Card) — Filed by lawful permanent residents to replace a lost, stolen, expiring, or damaged green card. Can be filed online through myUSCIS. Verify the current fee at uscis.gov.
USCIS Filing Fees in 2026
USCIS implemented its largest fee schedule update in years in 2024, with significant fee increases on most forms. Fees are subject to further change. Always verify current USCIS filing fees at the official fee schedule (Form G-1055) before filing any application or petition. A filing submitted with an incorrect fee will be rejected and returned, costing weeks of processing time.
Fee waiver eligibility exists for certain forms. Form I-912 (Request for Fee Waiver) may be filed by low-income applicants for eligible forms, though not all forms qualify for fee waivers. The N-400 naturalization application offers a reduced fee for applicants with household income between 150% and 200% of the federal poverty guidelines. Verify current fee waiver eligibility for your specific form before filing.
USCIS accepts payment by check, money order, and credit card via Form G-1450 (Authorization for Credit Card Transactions). For concurrent filings — such as an I-485 filed together with an I-765 and I-131 — fee calculations can be complex because certain forms filed concurrently with the I-485 may be covered under the I-485 filing fee. Always confirm the total fee due using the current fee schedule and the specific form instructions before mailing a filing package.
How to Contact USCIS
Reaching USCIS can be one of the most frustrating parts of the immigration process. Understanding the available contact channels and what each one can accomplish helps set realistic expectations.
The USCIS Contact Center
USCIS operates a Contact Center at 1-800-375-5283 (TTY 1-800-767-1833). Hours and language options are published at uscis.gov/contactcenter. The Contact Center can provide case status information, help schedule USCIS appointments at field offices, accept case service requests for cases outside normal processing times, and answer general procedural questions.
The Contact Center cannot speed up adjudication, provide individualized legal advice, or override field office decisions. Have your USCIS receipt number ready before calling. Expect significant wait times during high-volume periods — calling early in the day or midweek tends to produce shorter wait times, though this varies.
InfoPass Appointments
USCIS has moved away from walk-in InfoPass appointments at field offices. Most in-person USCIS appointments are now scheduled through the Contact Center based on demonstrated need. Situations that may qualify for an in-person appointment include emergent travel needs requiring expedited advance parole, proof-of-status issues affecting employment or benefits, cases with imminent deadline complications, and document issues that cannot be resolved through mail or the online portal.
Submitting a Case Inquiry Online
The online case service request tool at egov.uscis.gov/e-request allows applicants to inquire about cases outside normal processing times, report non-receipt of cards or documents, update appointment scheduling, and request the status of an emergency advance parole request. For non-emergency inquiries, the online tool is often more efficient than the phone line and creates a documented record of the inquiry.
USCIS Ombudsman
The DHS Office of the Citizenship and Immigration Services Ombudsman provides case assistance for cases experiencing prolonged delays or procedural problems that the USCIS Contact Center cannot resolve. The Ombudsman operates independently from USCIS and can intervene when standard channels have failed. Filing a case assistance request with the Ombudsman is sometimes the most effective option for cases that have been pending far beyond normal processing times with no explanation.
USCIS Field Offices and the New York Field Office at 26 Federal Plaza
USCIS operates roughly 80 field offices nationwide. Field offices handle interviews for adjustment of status, naturalization, and certain other case types. Service centers, by contrast, process paper-filed and electronically filed petitions that do not require an in-person interview. The distinction matters because field office processing times for interview-dependent cases can differ significantly from service center processing times for the same form.
The USCIS New York field office at 26 Federal Plaza in lower Manhattan is one of the highest-volume field offices in the country and processes most NYC-area cases, including marriage-based green card interviews, naturalization interviews, and removal of conditions interviews. For practical guidance on what to expect at the New York field office, see our posts on the marriage green card interview and what happens if you miss your USCIS interview.
Responding to USCIS Requests for Evidence (RFEs) and Notices
USCIS communicates with applicants through a series of standardized notice types. Understanding what each notice means — and what it requires — is critical for keeping a case on track.
Form I-797 Notice of Action — This is the generic USCIS notice form used for receipt notices (confirming filing), approval notices, biometrics appointment notices, and interview scheduling notices. Different I-797 subtypes (I-797C for receipts, I-797A for approvals with an I-94, I-797B for approvals of petitions) serve different functions.
Request for Evidence (RFE) — An RFE means USCIS needs additional information before adjudicating the case. It specifies exactly what evidence is needed and sets a response deadline, typically 87 days. The response must address every point raised in the RFE — incomplete responses often result in denial.
Notice of Intent to Deny (NOID) — A NOID means USCIS believes the case should be denied but is providing an opportunity to address specific concerns before making a final decision. The response deadline is typically 30 days. NOIDs are more serious than RFEs — they indicate USCIS has already formed a negative preliminary view of the case.
Notice of Intent to Revoke (NOIR) — A NOIR applies to already-approved petitions, typically I-130 or I-140, that USCIS now believes should be revoked based on new information, fraud concerns, or error in the original adjudication.
Denial Notices — A denial notice identifies the specific basis for denial and the available next steps. Depending on the form type, options may include filing a motion to reopen (with new facts), a motion to reconsider (arguing legal error), or an appeal to the Administrative Appeals Office (AAO).
For RFE response strategy: respond completely and on time. A partial response or a response that misses the deadline typically results in denial based on the record as it stood. Complex RFEs — particularly those questioning the bona fides of a marriage, the qualifications of a beneficiary, or the legitimacy of a business relationship — benefit from attorney review before response. For further reading on handling delays and insurer—or agency—level tactical considerations, see our post on marriage green cards for Iranian-American couples, which covers unique documentation challenges.
USCIS Policy Manual and Official Guidance
The USCIS Policy Manual is the consolidated source of current USCIS adjudication policy. It replaced the legacy Adjudicator’s Field Manual in 2020 and is updated regularly — sometimes multiple times per month. USCIS officers adjudicate cases under current Policy Manual guidance, which means the standards applied to a case may differ from those in effect when the case was filed.
Policy alerts notify the public of significant Policy Manual updates. For anyone tracking USCIS policy changes — immigration attorneys, HR professionals managing employment-based cases, and applicants in categories affected by frequent policy shifts — the policy alerts page is essential reading.
USCIS FOIA Requests
USCIS accepts Freedom of Information Act (FOIA) requests for immigration records through its FOIA/Privacy Act portal. FOIA requests are useful for obtaining your own immigration file (A-File), which contains the full record of your interactions with immigration agencies; reviewing records related to a previously denied case before refiling; obtaining copies of prior applications when originals have been lost; and supporting legal proceedings where the government’s administrative record is relevant.
FOIA requests are filed using Form G-639 (Freedom of Information/Privacy Act Request). Processing times for USCIS FOIA requests vary widely and can extend many months to over a year, depending on the complexity of the request and the current backlog. Expedited processing is available in limited circumstances. Applicants planning to refile a denied case should submit the FOIA request well in advance of any filing deadline.
Other Essential Government Resources
Beyond USCIS itself, several government resources surface regularly in immigration practice. Each serves a distinct function.
- Travel.State.Gov — Visa bulletins, consular processing information, country reciprocity schedules, and the U.S. embassy and consulate directory.
- Visa Bulletin — Published monthly by the Department of State, showing immigrant visa availability by category and country of chargeability. Essential for anyone in a preference category (EB-2, EB-3, F2A, F2B, etc.) tracking when a visa number will become available.
- EOIR Automated Case Information — Case status for immigration court matters. Individuals in removal proceedings check hearing dates and case outcomes here, not on the USCIS website.
- CBP One App — Customs and Border Protection’s mobile application for certain border-related processes.
- U.S. Department of Labor / Foreign Labor Certification — PERM labor certification and prevailing wage determinations for employment-based green card cases.
- Selective Service Registration — Required for male lawful permanent residents and certain other noncitizens between 18 and 25. Failure to register can affect future naturalization eligibility.
- Social Security Administration — SSN applications by work-authorized noncitizens. Some adjustment of status applicants can request an SSN during the I-485 process; others must apply separately at a local SSA office after receiving work authorization.
When to Use Self-Service Tools vs. When to Hire an Immigration Attorney
Not every immigration case requires an attorney. The USCIS self-service tools, online filing, and form instructions are genuinely accessible for many straightforward cases. A U.S. citizen filing an I-130 for a spouse with a clean immigration history, straightforward documentation, and no complicating factors can often navigate the process successfully using the resources described in this guide.
An immigration attorney becomes valuable when the stakes of a wrong filing exceed the filing fee. Specific situations where legal counsel is a sound investment include: prior immigration violations, overstays, or removal history that may trigger inadmissibility grounds; any criminal history, even minor offenses, that could affect eligibility; an RFE, NOID, NOIR, or denial that requires a strategic legal response; complex eligibility analysis such as extraordinary ability petitions, national interest waivers, or cases involving unclear documentation from countries with limited civil records; active or prior removal proceedings or a final order of removal; waiver applications (Form I-601, I-601A, I-212, I-192) that require proving extreme hardship or other legal standards; and cases that have exceeded normal processing times with no explanation from USCIS.
The cost of a complex immigration case being mishandled — denial, accrual of unlawful presence, loss of status, or initiation of removal proceedings — typically exceeds the cost of competent legal representation by orders of magnitude. For applicants in the New York area facing any of these complications, consulting a New York immigration lawyer early in the process is the most efficient use of time and resources.
