A denied Form N-400 is not the end of the road. The law gives applicants an administrative hearing and, after that, a full new review by a federal judge. The deadlines are short, and missing the first one can close the door, so it pays to know the sequence before a decision arrives.

Step one: the N-336 request

USCIS’s Form N-336 page says you should file the request for a hearing within 30 calendar days of receiving the denial, or 33 days if the decision was mailed. USCIS generally rejects late requests and does not refund the fee, although a late filing that meets the requirements for a motion to reopen or reconsider may be treated that way.

Because this deadline is counted in days, a paper filing that would be due on a weekend or federal holiday runs to the next business day under USCIS’s current guidance; see our report on the October 2026 deadline rule.

The administrative hearing

The hearing is held before an immigration officer under section 336 of the Immigration and Nationality Act. It is a chance to correct the record: bring missing documents, explain inconsistencies and address the specific reasons in the denial. Review the denial notice line by line and answer each ground with evidence.

Step two: federal court

If the officer affirms the denial, 8 U.S.C. 1421(c) allows review in the U.S. district court for the district where you live. The regulations at 8 CFR 336.9 require the petition within 120 days after USCIS’s final determination, and the review is de novo: the court makes its own findings of fact and conclusions of law and may hold a new hearing at the applicant’s request.

Denial or delay? Different tools

A denial and a delay call for different remedies. When USCIS has not decided within 120 days after the interview, the issue is a delay under 8 U.S.C. 1447(b), explained in our article on N-400 delays, 1447(b) and mandamus. When a lawsuit forces a decision and the answer is no, review runs through the N-336 and section 1421(c); mandamus.com explains what happens after mandamus produces a denial.

Avoiding a denial in the first place

Many denials trace back to preventable errors. See common citizenship application mistakes and our N-400 overview before you file or attend the interview.

Frequently asked questions

Can I go straight to federal court after a denial? No. 8 CFR 336.9(d) requires exhausting the N-336 hearing before judicial review.

How long do I have to sue after the N-336 decision? The regulation sets a period of not more than 120 days after USCIS’s final determination.

Will the judge only look at USCIS’s file? No. Review is de novo, and the court may hold its own hearing at the applicant’s request.
