The US Embassy in Bangkok processes US visa applications for all persons in Thailand and decides on the approval or rejection of each individual case after an interview with the applicant.

On this page, we offer you a comprehensive guide to applying for a US visa, which will help you understand the process of submitting a US visa application from Thailand and participating in the interview at the US Embassy in Bangkok, so that you can avoid common mistakes and prevent unnecessary delays.

Visa types available at the US Embassy in Bangkok

The US Embassy in Bangkok issues two main types of visas, depending on whether your stay in the US is temporary or permanent:

  • Nonimmigrant visas: These visas are for individuals who wish to stay temporarily in the United States. Common reasons include tourism, business trips, medical treatment, attending school, or participating in exchange programs.
  • Immigrant visas: These visas are for people who plan to move to the USA permanently. With this visa, you can apply for a Green Card and, over time, enjoy many of the same rights as US citizens.

    • List of the most frequently applied-for US visas at the embassy

    When applying for a visa at the US Embassy in Bangkok, you must select the visa that best suits your purpose of travel and planned length of stay. Here are the most common visa options:

  • US Tourist Visa: The US tourist visa allows short stays in the USA. It is valid for up to 10 years and entitles the holder to a stay of up to 180 days per entry. There are two main categories: US B1 Visa: For business trips, including meetings, conferences, and contract negotiations. US B2 Visa: For tourism, visiting friends or family, or medical treatment.
  • US E-2 Visa: The US E-2 visa is intended for individuals who wish to start or manage a business. It also applies to employees of E-2-registered companies.
  • K-1 Visa for the USA: The K-1 visa is for foreign fiancés of US citizens who wish to marry in the USA. It allows a 90-day stay, during which the marriage must take place. Afterward, the foreign partner can apply for a change of status to obtain permanent residency.
  • US K-3 Visa: The US K-3 visa is for foreign spouses of US citizens who wish to live in the US while their application for change of status is being processed. Holders of this visa can also apply for a work permit to work legally in the US.
  • US CR1 Visa: The US CR1 visa is for foreign spouses who have been married to a US citizen for less than two years. It leads directly to permanent residency; however, the foreign spouse must first complete a two-year probationary period in the US.

    • US visa application forms and how to submit them in Thailand

    Specific forms, supporting documents, and procedures apply to each type of US visa. While the exact steps depend on the visa type being applied for, you can generally expect the following process:

  • Application: Prepare all required documents and complete the appropriate visa application forms before submitting them online through the relevant U.S. government portal. The forms vary depending on the visa type, and some must be provided by the U.S. citizen, known as the "sponsor." U.S. Tourist Visa: Form DS-160; U.S. E2 Visa: Form DS-160; U.S. K-1 Visa: DS-160, Form I-129F (sponsor); U.S. K-3 Visa: Form DS-160, Form I-130 (sponsor); U.S. CR1 Visa: Form DS-260, Form DS-261, Form I-130 (sponsor).
  • Attend your interview: If you are applying for a U.S. visa in categories K1, K3, or CR1, you will receive further instructions regarding the documents you need to bring to your interview at the U.S. Embassy in Bangkok. For a U.S. tourist visa or an E2 visa, please print the application confirmation and bring it to your scheduled interview appointment at the U.S. Embassy in Bangkok. If the consular officer approves your application, the visa will be issued.

    • Keep in mind that the application process can take anywhere from a few weeks to several months. Therefore, if you are planning a trip to the USA soon, it is advisable to submit your visa application as early as possible.

    Required documents for the interview at the US Embassy in Bangkok

    Just as each visa type requires its own application forms, you will also need to compile the necessary documents for your interview at the U.S. Embassy in Bangkok. The requirements vary depending on the visa type, so be sure to check the specific list for your category. Below is a general overview of the documents most applicants should prepare:

  • Photos: Two recent photos taken within the last 6 months.

  • Court and prison records (if applicable): If you were convicted of a crime, you must provide certified copies of all relevant court and prison records, even if you were later granted a pardon, amnesty, or other form of sentence reduction. Include the section of the law under which you were convicted that specifies the maximum sentence, along with certified English translations.
  • Birth certificate: The original and a copy of the birth certificate. If no official Thai birth certificate is available, please submit the original birth certificate along with a copy.
  • Name change certificate(s): The original certificate(s) and one copy. Please arrange the certificates in chronological order, from oldest to newest.
  • Documents for US visa categories: These are all documents relevant to your visa, such as a marriage certificate for the US K3 visa and the US CR1 visa.

  • Applicant's documents (if applicable): If your visa has an applicant, you may need to provide documents such as the applicant's birth certificate, marriage certificate, job offer, or proof of their relationship to you.

    • It is important to note that if the original document is unavailable, a certified copy may be accepted. Furthermore, all non-English documents must be accompanied by a notarized, translated, and legalized English translation to be recognized by the U.S. Embassy in Bangkok.

    Guide to applying for a US visa in Bangkok

    Before you can attend your visa appointment at the US Embassy in Bangkok, you must follow all the steps outlined in the application process. Arriving unprepared may lead to delays or a rescheduled appointment.

  • Determine your visa type. Find out if you need a nonimmigrant visa (tourist, business, student, etc.) or an immigrant visa (spouse, fiancé(e), or family visa). Carefully review the eligibility criteria.
  • Application forms for nonimmigrant visas: Complete form DS-160 online and save the confirmation page. Immigrant visas: Complete all required forms (e.g., DS-260, DS-261, I-130, or I-129F) according to the visa category.
  • Pay the application fee. The visa fee can be paid at an authorized bank branch or online via electronic transfer (EFT). Keep the payment receipt – it will be needed to book your interview. If you are applying for an immigrant visa, you must pay the immigration fee online after your visa has been granted. This fee covers the processing of your visa application and the issuance of your permanent resident card (Green Card).
  • Gather the required documents: Collect all necessary documents (passport, photos, police clearance certificate, financial documents, etc.). Ensure that all non-English documents are notarized, translated, and legalized.
  • Schedule your visa appointment. Use the U.S. Visa Information and Appointment Service website to book your appointment at the U.S. Embassy in Bangkok. Print your appointment confirmation.
  • Complete the medical examination appointment form (for immigrant visas only) and attend an examination with one of the doctors listed on the U.S. Embassy in Bangkok website. Please do this at least 10 business days before your interview to ensure the results are available in time.
  • Attend your visa interview. Arrive at the embassy at least 15 minutes before your appointment to go through security. Please bring the following: appointment confirmation, confirmation page of the DS-160 or DS-260 form, all required documents, passport, two recent passport photos, and medical examination results (if applicable).
  • During the interview: Your fingerprints will be taken. A consular officer will ask you questions about your application and the accompanying documents.
  • Please wait for the decision. The officer will inform you at the end of the interview whether your visa application has been approved, denied, or is still being processed. Most decisions on nonimmigrant visas are made within a few days, while immigrant visas can take several weeks to process.
  • Receive your passport and visa. Once approved, your passport, stamped with the visa, will be delivered to your chosen DHL location in Thailand (usually within 7–10 working days).
  • Payment of final immigration fees (immigrant visas): When applying for an immigrant visa, you must pay the immigration fee online after the visa has been granted. This fee covers the processing of your visa application and the issuance of your permanent resident card, also known as a Green Card.
