How to schedule USCIS appointment

USCIS states that its field offices do NOT allow walk-ins: you must have an appointment to visit an office.

  1. Automatic notices (biometrics, interviews): USCIS sends by mail
  2. InfoPass appointment: for in-person inquiries — request one through your USCIS online account at my.uscis.gov, or call the USCIS Contact Center at 1-800-375-5283 (TTY 1-800-767-1833)
  3. Emergencies: call USCIS Contact Center 1-800-375-5283

What to bring

For a biometrics (ASC) appointment, USCIS says to bring:

  • Your biometric services appointment notice (or notices, if you have more than one)
  • Valid, unexpired photo identification — for example a Green Card (Form I-551), passport or driver’s license, or other identity documentation as authorized by USCIS

For an interview at a field office, bring what your interview notice lists. Source: USCIS — Application Support Centers.

Field Offices vs Application Support Centers (ASC)

  • Field Offices: offices that, per USCIS, hold interviews for all non-asylum cases (for example, getting a Green Card), naturalization ceremonies, and appointments for information and applicant services. The number varies by state: California, Florida and New York each have several, while a few states (for example Delaware, North Dakota and West Virginia) have none and are served by an office in a neighboring state.
  • ASCs: smaller centers only for biometrics.

How to know where your appointment is

  • Your USCIS appointment notice (Form I-797C, Notice of Action) shows the date, time and location
  • In your USCIS online account you can change your address and reschedule biometrics appointments

Address change (CRITICAL)

If you move AFTER submitting your USCIS petition:

  1. Change address via Form AR-11 (online: uscis.gov/ar-11). USCIS says that if you are an alien in the United States you must report any change of address within 10 days of moving, and that this requirement does not apply to A and G visa holders and visa waiver visitors.
  2. Notify USCIS for each pending case (myUSCIS account → Update address)
  3. Verify mail forwarding (USPS Change of Address)

USCIS emergency contacts

  • Senator/Congressman office — can help with stalled cases or problems (free, contact your representative)
  • USCIS Ombudsman: for systemic issues
  • CIS Ombudsman Case Assistance Form: dhs.gov/case-assistance
  • Attorney/BIA-accredited rep: for complex cases

Keep your info current

  • Name change (marriage, divorce): Form I-90 for green card or N-565 for naturalization certificate
  • Job change (if work visa case): notify via sponsor attorney
  • Status or program change (DACA expired, asylum granted): update immediately
