USCIS processing times at this office

USCIS publishes these times for the Guam office. Each figure is, per USCIS, the time it took to complete 80% of adjudicated cases in that category at this office over the last six months; the "comparison" column counts, among the field offices with a figure for the same category in our data read from that tool, how many show a shorter time. Our data may not include every office USCIS publishes.

Cases at the Guam office: April–June 2026 (USCIS fiscal year 2026, third quarter)

Under its Immigration and Citizenship Data, USCIS publishes, by field office, how many Form N-400, I-485 and I-130 cases were received, approved, denied and pending. These are the figures its files give for the Guam office (code AGA):

FormReceivedApprovedDeniedPending on June 30, 2026
N-400, naturalization (all)18212D901
I-485, green card through adjustment of status (all)18743051,237

I-130, petition for a relative (all)1455821,725
— of which immediate relatives of U.S. citizens119572639
  • Pending naturalization (N-400): rank 86 of 90 field offices (1 = the most pending among those 90 field offices; tied offices share a rank).
  • Pending adjustment of status (I-485): rank 86 of 90 field offices (1 = the most pending among those 90 field offices; tied offices share a rank).
  • Pending relative petitions (I-130): rank 86 of 90 field offices (1 = the most pending among those 90 field offices; tied offices share a rank).

"D" means USCIS does not publish that figure ("Disclosure standards not met"). Per USCIS's notes, some cases approved, denied or pending may have been received in earlier reporting periods; "pending" means awaiting a decision at the end of the quarter, and the report does not reflect some actions, such as administrative closures and transfers between offices. USCIS also notes that the office location does not reflect the complete area covered by the office's jurisdiction, that the figures are the most up-to-date estimate available when its database is queried, and that counts may differ from previous periods due to system updates and post-adjudicative outcomes. The N-400 file's heading prints "April 1, 2025 - June 30, 2026", but its file and sheet names identify fiscal year 2026, third quarter, the same period (April 1 - June 30, 2026) the I-485 and I-130 files print. The rank is our own count from the same figures. Sources: USCIS files for N-400, I-485 and I-130, published under Immigration and Citizenship Data; read October 17, 2026.

What USCIS says about visits

  • Appointment only. USCIS states that its field offices do not allow walk-ins and that an appointment is required to visit an office. Its field offices page refers visitors to the interview or appointment notice to confirm the field office address for the visit.
  • What a field office does. Per USCIS, field offices in the U.S. and its territories provide interviews for all non-asylum cases (for example, getting a Green Card), naturalization ceremonies, and appointments for information and applicant services that supplement its website and phone help.
  • Closures. USCIS says offices may close because of inclement weather or unexpected events and encourages checking its Office Closings page before traveling.
  • Lawyers in person. Effective May 18, 2026, USCIS no longer permits attorneys and accredited representatives to participate remotely in field office interviews, except in limited circumstances.
  • Payments. USCIS says it does not allow people to come to a field office to make a payment; for the forms it accepts payment on at field offices, payment is mailed with Form G-1450 (card) or G-1650 (bank account); for those who qualify for a paper fee payment exemption, USCIS says payment by check is possible by filing Form G-1651. The exception it names is emergency advance parole (Form I-131, EAP): USCIS says applicants call the Contact Center to make that appointment.
  • Fingerprints (biometrics). Taken at an Application Support Center (ASC) when USCIS schedules them. USCIS sends the appointment notice by mail or to the online account, and its ASC pages say to wait for that notice before visiting.

Appointments and rescheduling, per USCIS

  1. Field office appointment: USCIS’s field offices page links an online appointment request; the USCIS Contact Center is at 800-375-5283 (TTY 800-767-1833).
  2. Reschedule biometrics: USCIS’s biometrics page says the request must be made through your USCIS online account (not by mail), at least 12 hours before the appointment, and must establish good cause. It says to call the USCIS Contact Center at 800-375-5283 (TTY 800-767-1833) if the request is less than 12 hours from the appointment time, if the appointment was missed, or if there are problems making the request in the online account. If the request is not made before the appointment or good cause is not established, USCIS says it may consider the case abandoned and may deny it.
  3. Change of address: USCIS’s Form AR-11 page says an alien in the United States must report any change of address to USCIS within 10 days of moving, and that this requirement does not apply to A and G visa holders and visa waiver visitors. More on change of address. USCIS’s file assigns the field office by ZIP code.

Application Support Centers (biometrics) for this office’s ZIP codes

Fingerprints, photos and signatures are taken at an Application Support Center (ASC). USCIS’s field-office-by-ZIP file (dated August 28, 2026) also names an ASC for each ZIP code. For the ZIP codes it assigns to the Guam Field Office, the file lists two ASCs, ordered here from the most of this office’s ZIP codes to the fewest:

Each ASC’s USCIS page says applicants need to appear at the assigned ASC on the appointment notice, and USCIS’s biometrics page says an appointment at a different ASC without rescheduling will not be processed. ASC pages checked October 17, 2026; the full list is on USCIS’s Application Support Centers page.
