USCIS Phoenix field office: N-400 citizenship numbers and wait

USCIS's Phoenix field office (PHO, Arizona) had 10,819 N-400 citizenship applications pending at the end of June 2026, up from 9,905 at the end of March 2026. From April to June 2026 it approved 1,003 and denied 108 while 1,900 new applications came in.

These are USCIS's own quarterly counts. For the wait, USCIS's processing times page gives its own estimate for the Phoenix office (choose Form N-400), and your interview notice, not this page, tells you your date.

How long Phoenix takes

USCIS's quarterly counts don't include a wait time. For USCIS's own estimate, use its processing times page and choose Form N-400 and the Phoenix field office. Your interview notice gives your actual date.

Your citizenship interview at Phoenix

• Field offices don't take walk-ins. You need an appointment, and your interview notice gives the place and time.
• The officer puts you under oath, goes through your N-400 and gives the English and civics tests. See what the officer asks, part by part and all 128 civics questions.
• Since May 18, 2026, lawyers and accredited representatives must attend field office interviews in person, except in limited circumstances.
• You get a written result (Form N-652) at the end: approved, continued (for documents or a retest 60 to 90 days later) or denied.

Check your own case

• USCIS field office locator (search by ZIP code): USCIS no longer has a page per office, so this is where to confirm which office serves your ZIP code. Your interview notice gives the address.
• USCIS processing times (pick Form N-400 and your field office): USCIS's own estimate for your office, updated separately from these counts.
• USCIS Immigration and Citizenship Data: the quarterly tables these numbers come from.
