US K1 Visa

If you are a US citizen planning to marry your Thai fiancé(e) in the US, the US K-1 visa is the ideal option. This visa gives your Thai partner 90 days to enter the US, legally marry you, and then apply for permanent residency.

This page provides a detailed overview of the visa, its requirements, the roles of partners, and the application process. The better you understand this visa, the higher the likelihood that your application will be approved and that you and your partner can begin your new life in the USA as soon as possible.

What is the US K-1 visa and who is it for?

The US K-1 visa allows the foreign fiancé(e) of a US citizen to enter the US to marry within 90 days of arrival. If the marriage does not take place within this period, the visa expires and a new application must be submitted.

After marriage, the foreign partner can apply for a change of status to obtain permanent residency. This visa is specifically designed for fiancés of U.S. citizens who wish to marry in the U.S., providing them with a straightforward path to legal residency after the marriage.

If your fiancé(e) has children, they may, under certain conditions, obtain a US K2 visa, which allows them to accompany your fiancé(e), the holder of the K1 visa, to the USA.

If you are already married to a Thai spouse, this visa is not suitable for you. Instead, you will need to apply for a US K-3 visa or a US CR1 visa to bring your spouse to the United States.

What advantages does the US K-1 visa offer for your Thai fiancé(e)?

That covers the basics of the US K-1 visa. Now let's look at the advantages this visa offers your fiancé(e) after entering the USA. With the US K-1 visa, your fiancé(e) can:

  • Legally enter the USA to get married there
  • Stay in the USA for 90 days, during which you both must get married.
  • After marriage, apply for permanent residency through a status adjustment.

    • The K1 visa, however, is not:

  • Automatic granting of an unlimited residence permit – this only allows your fiancée to get married and then apply for a residence permit.
  • Allow your fiancé(e) to start working immediately upon arrival. To work in the U.S., he/she must first apply for a work permit.

    • What are the requirements for obtaining a US K-1 visa?

    There are two roles you and your fiancé(e) must assume: the role of the U.S. guarantor (you) and the role of the applicant (your Thai fiancé(e)). As guarantor, you must do the following:

  • Complete all necessary documents and begin the visa process by submitting an application (Form I-129F) to the US Citizenship and Immigration Services (USCIS).
  • Provide your fiancé(e) with financial support and meet the income requirements.
  • Prove that your income (or that of the sponsor) is at least 125% of the poverty line in your state.

    • For your fiancé(e), you must fulfill the following requirements:

  • Attend the interview at the US Embassy in Thailand and pass it.
  • I have passed a criminal record check and a medical examination.

    • Now, let's look at the admission requirements that you both must meet:

  • A foreign couple and a US couple
  • We have met in person over the last two years.
  • Are you planning to get married within 90 days of your arrival in the USA?

    • What documents are required to apply for a US K-1 visa from Thailand?

    Now that you know what roles you and your fiancé(e) will have to take on and what requirements must be met, here is a list of the documents you both need to submit for the US K-1 visa application:

  • A fully completed and signed Form I-129F
  • 1 passport photo of you, the sponsor
  • 1 passport photo of your fiancée
  • Proof of your (the sponsor's) citizenship, such as a birth certificate and a valid passport.
  • Proof that you and your fiancé(e) have legally terminated any previous marriage (if applicable).
  • Evidence or statements from both of you confirming your intention to marry within 90 days of your arrival in the USA.
  • Proof that you have both met within the last 2 years, or proof that an exception applies.

    • It is important to note that the documents must be in English. This means that all Thai documents you possess—be it your marriage certificate or the divorce decrees from your Thai spouse's previous marriages—must be notarized, translated, and legalized before you can use them for your US K-1 visa application.

    What is the application process for a US K-1 visa from Thailand?

    The entire application process can take 12 to 18 months, so be prepared for your wedding in the US to take a little longer. However, understanding the process and requirements can help you avoid further delays that would otherwise derail your wedding plans. Here are the individual steps of the K-1 visa application process from start to finish:

  • As a sponsor, you must submit an application (Form I-129F) to USCIS.
  • Once approved, the application will be forwarded to the National Visa Center for further processing before being forwarded again to the US Embassy or Consulate in Thailand, where your Thai partner will receive a BNK or application number.
  • The embassy or consulate will then send you and your fiancé(e) a letter with instructions on how to prepare and submit the application documents, which include a background check and a medical examination. An interview for your fiancé(e) will also be arranged.
  • After passing the interview, your Thai fiancé(e) will receive the US K1 visa and have 6 months to enter the USA.

    • The interview for the US K-1 visa will most likely include questions about your relationship, particularly your marriage plans after your fiancé(e) arrives in the US. This is to verify the legitimacy of your relationship and your visa application. Failure to answer these questions may result in the denial of your US K-1 visa.
