What USCIS may be checking

Whether the spouse was a U.S. citizen for the required period, whether the marriage still exists, and whether the couple lived in marital union during the relevant three years.
USCIS may compare N-400 answers with I-751 history, tax filing status, lease or deed records, address history, and interview statements.

Evidence to collect in a clean order

Spouse citizenship proof, marriage certificate, divorce/death records for prior marriages, joint tax transcripts, lease or mortgage records, insurance, bank or utility records, children’s records, and address timeline proof.
If there were separations, different mailing addresses, work travel, or amended tax returns, the response should explain rather than ignore them.

When the strategy may need to change

If the three-year rule is weak, it may be safer to analyze whether the applicant also qualifies under the five-year rule before sending a broad but inconsistent response.
A pending separation, divorce filing, prior I-751 issues, or conflicting address/tax records should be reviewed before the RFE response is filed.

Frequently Asked Questions

What does a three-year-rule RFE usually ask for?

It usually asks for proof of spouse citizenship, current marriage, marital union, shared residence, and timing under the three-year naturalization rule.

Can I switch from the three-year rule to the five-year rule?

Sometimes the record can be analyzed under the five-year rule, but the strategy depends on filing date, eligibility, and the exact RFE language.

What if we had different addresses?

Different addresses do not always defeat eligibility, but the reason and supporting proof should be organized before responding.
