ABOUT THE PHILADELPHIA FIELD OFFICE
The Philadelphia Field Office serves one of the oldest and most historically diverse immigrant communities on the East Coast. The Philadelphia metro has significant Cambodian, Vietnamese, Dominican, Liberian, and South Asian immigrant populations, and the city's historic role as a refugee resettlement destination means the naturalization applicant pool spans decades of arrival years. At 8 months as of May 2026, Philadelphia is processing near the national range. Note for New Jersey residents: southern New Jersey is served by the Newark Field Office, not Philadelphia. Verify your assigned office using the USCIS office locator before filing.

FREQUENTLY ASKED QUESTIONS
Can I speed up processing at the Philadelphia Field Office? +
USCIS does not accept general expedite requests for N-400. The most effective approach is filing a complete, error-free application, attending all appointments as scheduled, and responding immediately to any USCIS requests. An RFE adds 3-6 months regardless of office speed.
What happens at the citizenship interview? +
The officer reviews your N-400, tests your English, and administers the updated 2026 civics test — 128 questions, up to 20 asked, 12 correct required to pass. The interview takes 20-45 minutes for prepared applicants. Bring originals of all documents you submitted with your application.
Does the Philadelphia Field Office handle New Jersey applicants? +
No. Southern New Jersey residents are served by the Newark Field Office, not Philadelphia. The Philadelphia Field Office primarily serves southeastern Pennsylvania and Delaware. Verify your assigned office at egov.uscis.gov/office-locator with your zip code.
Is Philadelphia faster or slower than Newark for N-400? +
As of May 2026, both Philadelphia and Newark process in 8 months — currently identical. Verify current figures at egov.uscis.gov as times update monthly.
