USCIS Field Office Directory and Official Timing Lookup
N-400 applicants attend a naturalization examination and interview. USCIS decides I-485 interview waivers case by case. When an interview is scheduled, timing varies by field office. Use the official USCIS processing-time selector for the exact form and office.
Which office handles your case? Your local field office is determined by the zip code where you live, not where you filed. If USCIS schedules an interview, the appointment notice identifies the field office. A transfer status alone does not establish that an interview is required.
How USCIS field office interviews work
USCIS reviews the filing. Use the official processing-time tool for the exact form, category, and office rather than a universal pre-interview clock.
USCIS may transfer a case between offices. Read the transfer notice; the public status alone does not disclose the reason or guarantee an interview.
If USCIS schedules an interview, the appointment notice states the date, location, and instructions. Biometrics and interview scheduling do not follow one fixed sequence for every case.
A USCIS officer reviews the application and asks case-specific questions. Bring the documents listed in the appointment notice.
USCIS may decide the case at or after the interview, request evidence, or continue review. There is no universal post-interview decision clock.
