Frequently Asked Questions
Where do Michigan residents attend the naturalization interview?
The USCIS Detroit Field Office at 11411 E. Jefferson Ave, Detroit, MI 48214 handles interviews for all lower-peninsula Michigan applicants. Upper Peninsula residents interview at the Milwaukee or Sault Ste. Marie field offices depending on ZIP code.
How long does N-400 processing take for Michigan applicants?
As of 2026, the Detroit Field Office is processing 80% of N-400 cases in 6–10 months from filing. USCIS publishes current processing times per office at egov.uscis.gov/processing-times — always check before filing.
Can I travel outside the U.S. while my N-400 is pending?
Yes, but keep trips under 6 months to preserve continuous residence and be back in the U.S. for your biometrics appointment and interview. Trips of 6+ months can break continuous residence and reset the 5-year clock unless you filed Form N-470 in advance.
