N-400 Three-Year Rule

N-400 Three-Year Rule Marriage Evidence

Naturalization guide for green card holders filing under the three-year rule based on marriage to a U.S. citizen, including evidence and risk review.

Naturalization Risk Guide

Three-year naturalization filings need more than a valid green card

Applicants filing N-400 under the three-year rule usually need to show both permanent residence and a qualifying marital relationship with a U.S. citizen spouse. A weak marriage-evidence package can turn a citizenship filing into a broader relationship review.

Confirm the statutory timeline

Review the date permanent residence began, the spouse’s citizenship history, and whether the couple has lived in marital union for the required period.

Bring relationship evidence, not just certificates

USCIS may look for joint residence, taxes, bank records, insurance, children’s records, leases, mortgages, and other documents showing ongoing marital union.

Screen separation, travel, and tax issues early

Temporary separation, long trips, different tax addresses, or prior I-751 issues should be reviewed before filing instead of explained for the first time at interview.

How to use this guide

Before filing N-400 or attending an interview, collect the relevant notices, government records, tax records, travel dates, and relationship or court documents. A short attorney review can often identify whether the issue is routine, needs a written explanation, or should delay filing.
