Services available at this office
- Naturalization interviews
- Adjustment of status interviews
Field offices conduct interviews and resolve case-specific issues. Paperwork processing — receipt, evidence review, decision drafting — happens at a USCIS Service Center, not a field office. You will never visit a Service Center in person.
How to schedule an appointment
USCIS field offices do not accept walk-ins. There are three ways to get into the Buffalo field office:
- 1
Wait for a USCIS appointment notice
For most cases — naturalization (N-400), adjustment of status (I-485), removal of conditions (I-751) — USCIS schedules your interview automatically and mails an appointment notice. You don't need to call.
- 2
Request an appointment via the USCIS Contact Center
Call 1-800-375-5283 to request a non-emergency in-person appointment. The Contact Center will create a service request and schedule a slot if your reason qualifies.

- Your USCIS appointment notice (Form I-797C)
- A government-issued photo ID — passport, driver's license, or state ID
- Your green card (if you're already a lawful permanent resident)
- Original documents that match the copies you submitted with your application
- Any RFE (Request for Evidence) response materials

To request a non-emergency appointment, call the USCIS Contact Center at 1-800-375-5283 or submit a request through your USCIS online account at my.uscis.gov. Most interviews are scheduled automatically by USCIS — you'll receive a notice in the mail with the date, time, and instructions.
What services does the Buffalo field office provide?
The Buffalo Field Office typically handles naturalization interviews, adjustment of status interviews. Field offices are where most in-person interviews happen — naturalization (N-400), adjustment of status (I-485), and removal-of-conditions (I-751). Biometrics (fingerprints) are usually taken at a separate Application Support Center (ASC), unless this office has a co-located ASC.
Can I check the status of my case at the Buffalo office?
Yes, but the fastest way is online. Sign in to your USCIS account at my.uscis.gov or use the public Case Status Tool with your receipt number. In-person status inquiries at the field office require an appointment and are typically reserved for cases that are significantly outside normal processing times.
Is the Buffalo USCIS office the same as a USCIS Service Center?
No. Field offices handle in-person interviews and customer service. Service Centers (Texas, Vermont, Nebraska, California, Potomac) process paperwork only — they do not host visits or interviews. Your I-130 or I-140 receipt may show a service center address, but you'll never go there in person.
