K-1 fiancé(e) visa: requirements, process and CR-1 comparison

Wang Law Firm, LLC · David Wang, Managing Attorney

The K-1 visa lets the foreign fiancé or fiancée of a U.S. citizen come to the U.S. to marry. After entering on a K-1, the couple must marry within 90 days, and the petitioner must be the person the K-1 holder marries. After the wedding, the foreign spouse files I-485 inside the U.S. for a green card. The K-1 itself is a nonimmigrant visa, but its purpose is clear: enter, marry, and move on to a green card.

The K-1 suits couples who want to hold their wedding in the U.S. and live together there afterward. Its limits are just as clear: the K-1 holder can only marry the petitioner, can't change to another status after entry, and has to go through a separate adjustment of status process after the wedding. Whether it's a better fit than "marry first, then apply" depends on your circumstances; there's a comparison table below.

Who it suits

• The petitioner is a U.S. citizen (green card holders can't file for a K-1);
• The couple isn't yet married and plans to marry in the U.S.;
• The foreign fiancé(e) is currently outside the U.S. and will interview at a U.S. embassy or consulate;
• Neither partner has any legal impediment to marriage.

Requirements

1. The petitioner must be a U.S. citizen.
2. Both partners are legally free to marry: both are single, any prior marriages have legally ended by divorce, annulment or a spouse's death, and they meet the legal requirements (such as age) of the state where they'll marry.
3. A genuine intention to marry within 90 days of entry.
4. The couple must have met in person at least once within the two years before the I-129F is filed. There are only two limited waivers: meeting would violate strict, long-established customs of the foreign partner's culture or religion, or meeting would cause extreme hardship to the U.S. citizen. A waiver requires evidence and isn't easily granted.
5. The foreign partner has no inadmissibility issues (for example, certain criminal records, past immigration violations, or health or public charge issues).

If the U.S. citizen has certain specified criminal convictions (for example, involving domestic violence or crimes against minors), they must disclose them truthfully, and this may affect approval. There are also additional disclosure requirements and limits for petitioners who have filed multiple I-129Fs.

The process

1. File the I-129F: the U.S. citizen files the petition for alien fiancé(e) with USCIS, with proof of both partners' identity, proof that both are single, evidence of meeting within two years, and evidence of a genuine relationship.
2. USCIS approval: once approved, the case goes to the National Visa Center (NVC) and then to the U.S. embassy or consulate in the foreign partner's country.
3. Prepare the visa application: the foreign partner completes the DS-160 online, prepares documents such as a police certificate and notarial birth certificate, and has a medical exam with a panel physician designated by the consulate (see Immigration medical exams).
4. Consular interview: the consular officer verifies that the relationship is genuine and that the couple intends to marry, and reviews grounds of inadmissibility. The U.S. citizen usually needs to provide an I-134 declaration of financial support or other evidence of financial support, as the consulate requires.
5. Enter the U.S.: a K-1 visa is generally valid for a single entry, which must be made while the visa is valid.
6. Marry within 90 days: the K-1 holder can only marry the I-129F petitioner.
7. File the I-485: after the wedding, file the adjustment of status application with the I-864 affidavit of support, and apply for a work permit and reentry permit at the same time.

Documents you'll usually need

• Proof of U.S. citizenship (passport, naturalization certificate or birth certificate);
• Both partners' passports, proof of single status, and proof that prior marriages ended (divorce decrees and so on);
• Evidence of meeting within two years: flight tickets, boarding passes, hotel records, passport entry and exit stamps, and photos together;
• Evidence of a genuine relationship: messaging records, records of visits, engagement details, and a statement of the couple's wedding plans (a statement of intent signed by both can be included);
• At the interview stage: notarial birth certificate, police certificate, medical exam results, proof of financial support and so on. Chinese-language documents, for example, need complete English translations; see Translation requirements.

What happens if you don't marry within 90 days

The 90 days after entering on a K-1 can't be extended. If the K-1 holder doesn't marry the petitioner within 90 days, they must leave the U.S.; otherwise they begin to be unlawfully present and may be removed. K-1 holders also can't change to another nonimmigrant status inside the U.S. (such as F-1 or H-1B), and if they marry someone other than the petitioner, they can't adjust status inside the U.S. through that marriage.

If the couple marries within 90 days but doesn't file the I-485 right away, the K-1 holder doesn't necessarily lose eligibility to adjust status, but in the meantime they have no lawful status and can't work or travel. We recommend filing soon after the wedding.

K-2 children

Unmarried children under 21 of the foreign fiancé(e) (the K-1 visa holder) can apply for K-2 visas to come with or after the parent. No separate I-129F is needed, but the children must be listed on the I-129F. After entering, K-2 children also apply for green cards by filing I-485; their adjustment is based on the parent's marriage to the U.S. citizen. If a child is close to 21, pay special attention to timing, and consult an attorney if needed to calculate age-out protection.

Getting the green card after the wedding

A K-1 holder adjusting status after the wedding doesn't need a separate I-130; the I-129F has already served to establish the relationship. File the I-485 with the I-864, the medical exam (the pre-entry exam can be reused under certain conditions; check current USCIS rules), the marriage certificate and so on. If the marriage is less than two years old when adjustment is approved, you receive a two-year conditional green card and must file I-751 within the 90 days before it expires; see Marriage green card. To travel while the I-485 is pending, you must obtain a reentry permit (advance parole) beforehand; see Adjustment of status (I-485).

K-1 compared with marrying first and applying for CR-1/IR-1

Processing times for both change, and there's no fixed answer as to which is faster; rely on what USCIS and the State Department currently publish. For how to check fees and times, see How to check filing fees and processing times; for official K-1 information, see the State Department K-1 page.

Common mistakes and reasons for denial

• Insufficient evidence of meeting within two years: only chat records, with no objective record of actually meeting;
• Filing before a prior marriage has legally ended;
• Inconsistent relationship evidence, or being unable to describe basic facts about your partner at the interview;
• Assuming you can enter and decide later, and only wanting to marry after the 90 days have passed;
• Undisclosed visa refusals or overstays by the foreign partner.
