Many couples meet while travelling or working abroad, and then face the practical question of where they will live. For UK citizens who marry US citizens and want to build a life in the United States, relocating lawfully requires careful consideration and often, the correct type of visa. Understanding the main types of US marriage visas and how requirements like the 90‑day rule work is essential before making any firm plans.
What is a US Marriage Visa?
A US marriage visa is a route that allows the foreign spouse or fiancé/eé of a US citizen to enter the United States to marry and, ultimately, obtain permanent residence, rather than live apart.
When people talk about a “US marriage visa”, they can mean different types of visas, including temporary US visas, such as the K‑1 or K‑3, or I-130 green card petitions that provide a permanent resident ID. Each option has its own eligibility rules, timeframes and practical benefits and considerations for couples weighing up where and when to marry.
Main Types of US Visas for Couples
US immigration law offers several pathways for couples who want to live together in the United States. The most common solutions for UK–US couples are the K-1 visa, K-3 visa, and permanent resident petition. Choosing the right route depends on whether you are already married, where you plan to get married, and how quickly you want to move.
K‑1 Visa
The K‑1 visa is designed for a foreign national who is engaged to a US citizen and intends to get married in the United States. The US Consulate issues K-1 visas as a temporary visa, and they require the foreign fiancé/fiancée to contract marriage with a US citizen within 90 days of entry into the United States.
The US citizen must first file an I-129F petition, which demonstrates that the relationship is genuine, that the couple is free to marry, and that they intend to marry. To obtain a temporary residence petition, the couple must also provide evidence that they have met in person within the last 2 years, unless religious principles prevent them from meeting before the wedding.
Once the marriage has taken place, an adjustment of status to permanent residence can be made, enabling the married couple to live together in the US. For many, this route offers a straightforward path: enter the US on a K‑1, marry within the required period, then apply for US migration and green card status afterwards.
K‑3 Visa
The K‑3 visa is designed for foreign spouses who are already married to a US citizen but are waiting abroad for an immigrant visa to be processed. To reduce the separation of immediate family members of US citizens, the K‑3 non‑immigrant (temporary) visa was introduced.
This visa allows the foreign spouse to enter the United States as a non‑immigrant, live with the American spouse in the US, and then file Form I-485 for adjustment of status to permanent residence. In practice, the K‑3 can be seen as a bridge: it does not grant permanent residence, but it enables a married couple to reunite while the immigration process is undertaken.
Whether a K‑3 is appropriate will depend on processing times and how quickly the couple wants to relocate. It is not mandatory, and an application for immigrant status may be filed without it.
Direct Immigrant Spousal Route
A US spouse visa may also be obtained through a permanent resident petition and an immigrant visa application. In this scenario, the US citizen files a petition for their spouse, and once approved, the foreign spouse applies for an immigrant visa at a US embassy or consulate.
Upon arrival in the United States with this immigrant visa, the spouse becomes a lawful permanent resident and does not need any type of temporary visa first. For some couples, this can be the most straightforward option, particularly when timelines and evidence are clear, and no interim solution is needed.
However, it does mean remaining outside the United States until the entire immigration process is complete, which can sometimes be lengthy.
How the 90‑Day Rule Works
The 90‑day rule is well known, but many do not understand what it actually means. It is central to the K‑1 US marriage visa and is often one of the most misunderstood aspects of the process.
When a foreign fiancé/eé enters the United States on a K‑1 visa, they must marry the US citizen sponsor within 90 days of arrival. If they do not, they will usually be required to leave the United States and may not be able to change to another visa status from within the country. This timeframe is set by US immigration law to ensure the visa is used for its intended purpose: marriage to a US citizen and permanent residence.
The 90‑day rule means planning is essential. Couples should have realistic wedding plans in place before travelling to the US, including location, documentation and any religious or civil requirements. If the marriage does not take place within the 90‑day period, the K‑1 status expires, and remaining in the US without a valid status can lead to serious consequences.
Evidence Couples Need to Provide
For any US marriage or US Spouse visa, consular officers will expect clear evidence that the relationship is genuine and the legal requirements are met.
For K‑1 visas, couples will usually need:
- Proof they have met in person within the last two years, such as letters, emails, flight tickets, hotel bookings and phone bills.
- Evidence of a genuine relationship, such as photographs taken together over time and statements from family and friends.
- Proof of the engagement and clear intention to marry within 90 days of arrival in the United States.
For K‑3 and immigrant spousal cases, couples will usually need:
- A valid marriage certificate showing the marriage is legally recognised.
- Proof that the marriage is genuine and not solely for immigration purposes, such as wedding photographs, joint financial records, and other shared commitments.
- Complete documentation of any previous marriages to show both parties were free to marry at the time of the current relationship.
