K1 visa documents: the complete checklist

• ✓Valid passports for both of you (yours valid well beyond your planned entry).
• ✓Birth certificates, plus a certified translation if not in English.
• ✓Proof you have met in person: photos together, boarding passes, passport stamps.
• ✓Proof of an ongoing relationship: messages, call logs, visits, joint plans.
• ✓Evidence your fiancé(e) is a US citizen: passport or naturalization certificate.
• ✓Proof of the intention to marry within 90 days of arrival.
• ○The visa application form (DS-160) confirmation page and fee receipt.
• ○Two recent passport-style photos, to the current US specifications.
• ○Financial documents from the US side (affidavit of support and tax returns).
• !If either of you was married before: the final divorce decree or death certificate, translated.
• !Any police or court records, translated — do not hide anything, omissions cause delays.
