A USCIS Field Office handles immigration cases in your area

A USCIS Field Office is a local immigration office run by U.S. Citizenship and Immigration Services. It processes applications and petitions for people in its geographic region — things like green card applications, work permits, name changes, and citizenship interviews. When USCIS sends you a notice telling you to appear for an interview or biometrics appointment, that appointment usually happens at the field office that covers where you live or work.

Field offices are not the same as ports of entry or consulates. You do not go there to enter the country; you go there after you have already arrived and are working through the immigration system. Each field office serves a specific area, and USCIS assigns your case to the one with jurisdiction over your address.

Understanding what your local field office does and how to contact it matters because it is the place where your case gets reviewed, where you may have to show up in person, and where you can sometimes get answers about delays or missing documents.

Key Takeaways

  • Every USCIS case is assigned to a field office based on where you live, and that office handles interviews, biometrics appointments, and case decisions for your area.
  • You can find your local field office by entering your ZIP code on the USCIS office locator at uscis.gov, which also shows hours and phone numbers.
  • Field offices do not accept walk-in visits for most services; you must have a scheduled appointment notice from USCIS or call ahead to ask about in-person help.
  • If you need to contact your field office about a case, have your receipt number (the code starting with "EAC", "WAC", "LIN", or "SRC") ready before you call.
  • Some field offices offer limited in-person services for certain requests, but availability varies by location and you should check the office website or call first.

How to find your local USCIS Field Office

USCIS maintains an office locator tool on its website at uscis.gov/field-offices. You enter your ZIP code, and the tool shows you the field office that has jurisdiction over your area. The result includes the office address, phone number, hours of operation, and a link to that specific office's webpage.

The office assigned to you depends on where you live, not where you work or where you submitted your process. If you move, your case may be transferred to a different field office, though this can take time. If you are unsure whether your case has been transferred after a move, call the field office that currently covers your new address and give them your receipt number.

Some cities have more than one field office. The locator tool will show you which one serves your specific ZIP code. If you live near a border between two office jurisdictions, double-check the tool to make sure you have the right one.

What happens at your field office appointment

When USCIS schedules you for an appointment, the notice will tell you which field office to go to and what time to arrive. Most appointments fall into a few categories: biometrics (fingerprinting and photos), an interview for your process or petition, or a document review.

For a biometrics appointment, you arrive, provide your fingerprints and photograph, and answer basic questions to confirm your identity. The appointment usually takes 15 to 30 minutes. For an interview, a USCIS officer will ask you questions about your process, your background, and your may be able to access for the benefit you are seeking. Interviews can last anywhere from 20 minutes to over an hour depending on the case.

Bring the documents listed in your appointment notice. If you do not have something, call the field office before your appointment to ask whether you can bring it late or whether you need to reschedule. Missing documents can result in a denial or a request for evidence that delays your case.

Contacting your field office by phone or mail

Each field office has a phone number listed on the USCIS office locator. When you call, have your receipt number ready. The receipt number is a code that starts with "EAC" (Eastern), "WAC" (Western), "LIN" (Lincoln), or "SRC" (Southern) followed by numbers and a year. You can find it on any notice USCIS has sent you.

Call times vary by office, but most field offices have phone lines open during business hours, usually 8 a.m. to 4 p.m. Monday through Friday. Some offices have separate phone lines for different types of cases or questions. The office webpage will tell you which number to call for your situation.

You can also mail documents or requests to your field office. The mailing address is on the office webpage and on any notice USCIS sends you. Mail takes longer than a phone call, so use it only when you need a permanent record or when the office has asked you to mail something specific.

In-person services and walk-in help

Most USCIS field offices do not accept walk-in visitors. You must have a scheduled appointment. However, some offices offer limited in-person services for specific requests, such as replacing a lost green card, getting a copy of a document, or asking about a case status.

Before you go to the office in person, check the office webpage or call ahead. Ask whether the service you need can be handled in person and whether you need an appointment or can be seen on a first-come, first-served basis. Some offices have specific hours for walk-in services, and some do not offer them at all.

If you show up without an appointment and the office does not accept walk-ins, you will be turned away. Calling or checking the website first saves you a trip.

What to bring to your field office appointment

Your appointment notice will list the documents you need to bring. At minimum, bring a valid photo ID (passport, state ID, or driver's license) and your appointment notice itself. If you are bringing someone to interpret for you, bring their ID as well.

Bring originals of any documents USCIS asked for, plus one copy of each. Do not bring originals of documents you need to keep, such as your birth certificate or passport, unless USCIS specifically asked for them. If you are unsure, call the field office and ask.

Do not bring children unless they are directly involved in the case or you have no one to leave them with. Do not bring weapons, recording devices, or large bags. Rules vary slightly by office, so check the office webpage for specific restrictions.

Case processing times and status checks

USCIS publishes processing times for different case types on its website. These times are estimates and vary by field office and case complexity. You can check the processing time for your case type and office on uscis.gov/processing-times.

To check the status of your specific case, you need your receipt number. You can check online at uscis.gov/case-status or call your field office. Online status updates are usually faster, but the phone line can give you more detail if your case has a note or issue attached to it.

If your case is past the processing time estimate and you have not heard anything, call your field office. Bring your receipt number and ask whether the case is delayed, whether additional evidence is needed, or whether there is a problem with your file.

Frequently Asked Questions

Can I go to a different field office if the one near me has long wait times?

No. USCIS assigns your case to the field office that has jurisdiction over your address. You cannot choose a different office to speed up processing. If you move to a different area, your case may eventually transfer to the new office, but this is not automatic and can take weeks or months.

What if I miss my appointment at the field office?

Contact your field office when ready. Depending on the type of case and the reason you missed the appointment, USCIS may reschedule you or may deny your process. Call the office the same day if possible and explain why you could not attend. Bring documentation of the reason (medical emergency, work conflict, etc.) if you have it.

Can I bring a lawyer or representative to my field office appointment?

Yes. If you have an immigration attorney or accredited representative, they can accompany you to your appointment. Bring a copy of the Form G-28 (Notice of Entry of Appearance as Attorney or Accredited Representative) that you filed with USCIS. The representative can answer questions and help you present documents, but the officer may still ask you questions directly.

How do I know if my case has been transferred to a different field office?

USCIS usually sends a notice if your case is transferred, but the notice can take time to arrive. If you moved and are unsure, call the field office that now covers your new address with your receipt number. They can tell you whether your case is with them or still with the old office.

What if I need an interpreter at my field office appointment?

You can bring your own interpreter, or you can ask USCIS to provide one. If you want USCIS to provide an interpreter, call your field office at least two weeks before your appointment and request one in the language you need. Some offices charge a fee for this service. Bring a photo ID for your interpreter if you bring your own.
