K-1 · Fiancé(e) of US citizen
Only US citizens can file K-1 (LPRs cannot); the beneficiary must marry within 90 days of entry, then adjust status via I-485. The alternative is the CR-1 spouse visa — slower, but it lands as a green card instead of a two-step process.

Eligibility
Process
Confirm the petitioner is a US citizen (LPRs cannot use K-1), that both parties are legally free to marry, and that they met in person within the past two years. If the meeting cannot be evidenced, argue a cultural / religious / extreme-hardship waiver. Screen the petitioner for IMBRA multi-filing limits (≥ 2 prior K petitions → IMBRA waiver required).
Duration · 3–7 days
Complete I-129F, gather bona-fide-relationship evidence (joint photos, chat logs, mutual visits), in-person meeting proof (flights, entry stamps, hotel receipts), petitioner citizenship proof, and single-status / divorce records for both parties. Attach IMBRA disclosure. Mail to USCIS — I-129F is paper-only; there is no online filing path.
Duration · Prep 2–4 weeks · USCIS adjudication 9–15 months
Pull US passport / birth certificate / naturalization certificate; joint photos, chats, remittances, travel evidence with the fiancé(e). Document the two-year in-person meeting with objective records: flights, entry stamps, hotel folios.
Truthfully disclose criminal history, domestic-violence / sex-offense / restraining-order history, and any prior K or spouse-visa filings. USCIS shares this with the beneficiary — concealment can sink the case and taint future filings.
Passport, birth certificate, divorce decree (if applicable), police clearance certificates, prior US visa history. Compile relationship evidence — chats, joint photos, mutual-visit itineraries, joint accounts or remittance records.
Schedule the consular interview: submit DS-160 online, complete the K-visa panel-physician exam (separate from the I-693 civil-surgeon exam used later at the I-485 stage), bring originals, and answer bona-fide-relationship questions honestly. Both parties’ accounts of how they met and post-marriage plans must line up.
Duration · 1–4 weeks for visa issuance after the interview
After I-129F approval, the case routes through the NVC to the consulate in the beneficiary’s country. Walk the beneficiary through DS-160, panel-physician medical, police certificates, and the petitioner’s I-134 declaration of support (non-binding at the K-1 stage). Run a mock interview centred on bona-fide-relationship questioning.
Duration · 4–10 weeks
After entry, help arrange the marriage license (many states have a waiting period). Once married, file I-485 concurrently with I-864 (binding affidavit replacing I-134), I-693 (US-side civil-surgeon exam), I-765 EAD, and I-131 Advance Parole. Hard-rule reminder: do not depart the US until AP is in hand.
Before the interview, provide I-134 with 3 years of tax returns, an employment letter, and bank statements. K-1 stage uses the non-binding I-134; after marriage the I-485 stage requires the binding I-864.
Arrange the Marriage License, venue, and officiant. The legal wedding must occur within 90 days of entry; obtain the official Marriage Certificate. File the binding I-864 with the I-485 — this is an enforceable contract that survives divorce and runs until the beneficiary naturalises or earns 40 qualifying work quarters.
The K-1 visa is valid 6 months for entry. Once you enter, the 90-day clock starts and the marriage must happen inside that window. You cannot work legally until the EAD is issued. You cannot leave the US until Advance Parole is granted — K-1 is a single-entry visa, and departing without AP voids both the K-1 and the pending I-485.
After the wedding, file I-485 + I-864 + I-693 (US civil-surgeon medical) + I-765 EAD + I-131 Advance Parole as a single package. Attend biometrics; an interview is likely. Initial green card is conditional (2 years, because the marriage is under 2 years old) — file I-751 to remove conditions in the 90-day window before expiry.
Documents
Signed by the US-citizen petitioner. Paper-only — there is no USCIS online filing option for I-129F.
Flights, passport entry stamps, hotel folios, joint photos — proving an in-person meeting within the 2 years before filing.

Filed in the US after marriage. Initial green card is conditional (2 years); requires I-751 later to remove conditions.
Filed with I-485. A legally enforceable contract on the petitioner — survives divorce.
Used at the I-485 stage. Separate from the K-visa panel-physician exam taken at the consulate.
I-765 EAD authorises work; I-131 Advance Parole permits travel while I-485 is pending.
Timeline
| Stage | Duration | What can go wrong |
|---|---|---|
| I-129F filed + USCIS adjudication | 9–15 months | Thin relationship evidence or unprovable in-person meeting — frequent RFE trigger. Premium Processing is not available for I-129F. |
| NVC transfer + consular interview | 2–6 months | 221(g) for relationship documentation — both parties’ accounts of how they met and post-marriage plans must align. |
| K-1 visa issued + US entry | Enter within 6 months of issuance | K-1 is single-entry — leaving the US after entry without Advance Parole voids both the K-1 and the pending I-485. |
| Marry within 90 days of entry | ≤ 90 days from entry | Missed 90-day marry deadline — K-1 cannot be extended; the beneficiary must depart with no salvage path. |
| File I-485 + I-864 + I-693 + I-765 + I-131 | 6–14 months to green card | Travel before AP is approved → I-485 deemed abandoned. I-864 income below 125% of the federal poverty line → joint sponsor required. |
FAQ
K-1 typically gets the foreign fiancé(e) into the US sooner (12–18 months end-to-end versus 14–24 months for CR-1), but K-1 only delivers a non-immigrant entry visa — you then pay another $1,440 for I-485 to actually get the green card. CR-1 is one consular process that ends in a green card on entry, no I-485 step. Net result: K-1 is faster to reunite, CR-1 is cheaper overall and ends in immediate work authorisation. Choose K-1 if reunion speed matters most; choose CR-1 if you can wait and want to skip the AOS step.
Absolute. The 90 days runs from the day the beneficiary enters the US on K-1, and USCIS cannot extend it. If the marriage does not happen in time, the K-1 status lapses, the beneficiary must depart, and there is no fix from inside the US — no extension, no change of status to anything else. Plan around the state’s marriage-license waiting period (in some states up to 6 days between application and ceremony) and the I-485 prep schedule. Treat day 60 as the soft deadline.
Yes — unmarried children under 21 of the K-1 beneficiary qualify as K-2 derivatives on the same I-129F. They can enter with you or follow within 1 year of K-1 visa issuance. Each K-2 child needs their own DS-160 and consular interview, but no separate I-129F. After marriage they file their own I-485 alongside yours. The same 90-day-marry rule applies to the principal K-1 — the K-2 children inherit status from the K-1 parent.
If the relationship ends before the 90-day deadline, the K-1 beneficiary cannot stay in the US — there is no path to change K-1 to another status from inside the US for someone who did not marry the original petitioner. The beneficiary must depart. K-1 cannot be transferred to a new partner. The petitioner has no recourse beyond filing a fresh I-129F for a new fiancé(e) (and IMBRA multi-filing limits will apply).
A single concurrent package: I-485 (the green-card application, $1,440), I-864 (binding affidavit of support signed by the USC spouse, $0), I-693 (medical from a US civil surgeon — separate from the K-visa medical you already did at the consulate), I-765 (EAD, $260 with I-485), and I-131 (Advance Parole, $630 with I-485). The initial green card is conditional for 2 years because the marriage is under 2 years old at adjudication — you will later file I-751 to remove conditions in the 90 days before that card expires.
Not until Advance Parole (I-131) is approved. If you depart the US before AP is in hand — even for an emergency — USCIS will deem the I-485 abandoned, and the prior K-1 status will not be reinstated. Once AP is approved (combo card with EAD is now standard, roughly 4–8 months from filing), you can travel and re-enter as a parolee while I-485 stays pending. Keep the AP document and a copy of the I-485 receipt on you when you re-enter.
Yes — since Obergefell v. Hodges (2015) and the corresponding USCIS policy, K-1 treats same-sex and different-sex couples identically. The same eligibility rules apply: USC petitioner, both legally free to marry, met in person within 2 years, intent to marry within 90 days, bona fide relationship. Caveat: the marriage must take place in a US state or jurisdiction that recognises it (every US state does, post-Obergefell). Country-of-origin laws are irrelevant to USCIS adjudication.
