Important Notice: Starting from January 1, 2018, the Diplomatic/Official Visa Services Window is closed on the last Wednesday of each month. 

The Nonimmigrant Visa Unit in Bangkok maintains a Diplomatic and Official Visa Services Window for diplomats, national-level government officials, and International Organization employees traveling to the United States on official business who qualify for an A-1, A-2, G-1, G-2, G-3, G-4, or C-3 (diplomatic) visa. The window is open on Monday and Wednesday afternoons from 1:30 p.m. (13:30) until 3:00 p.m. (15:00) except for Thai and United States national holidays The Consular Section in Chiang Mai does not accept applications for A, G, or C-3 visas.

The determination regarding eligibility for one of the visa classifications listed above is made by a Consular officer and applicants will be instructed how to proceed if they do not qualify.

The diplomatic window provides services to travelers who are Official Representatives of:

  • The Royal Thai government;
  • Recognized International Organizations (IMF, World Bank, WHO etc.); or
  • Embassies or Consulates located in Bangkok.

Applicants who are being sent to the United States on official government or international organization business require a “Diplomatic Note” or “Note Verbale” from the sending organization or, in the case of Thai officials, from the Foreign Ministry. For officials of other countries who will be assigned to foreign missions in the United States, this diplomatic note should also originate from their government’s foreign ministry and not from an embassy.

This diplomatic note should include the following information concerning the principal applicant:

  1. Name and date of birth
  2. Position and title
  3. Place of assignment or visit
  4. Purpose of travel
  5. Brief description of duties
  6. Travel date
  7. Anticipated length of stay or tour of duty in the United States, and
  8. The names, relationships, and dates of birth of any dependents and other members of household who will be accompanying or joining the principal.

Procedures for Bangkok:

Applicants who believe they may meet the qualifications for a diplomatic or official visa should consult with their administrative offices that normally handle visa issues, and then complete the DS-160 Electronic Non-Immigrant Visa Application based on the diplomatic or official visa category for which they believe they will qualify, and print out the Confirmation page. They should submit the Confirmation page, their diplomatic or official passport, one photo, and a Diplomatic Note or Note Verbale from the Foreign Ministry or International Organization to the Diplomatic Window during the times specified above. Applicants DO NOT need to pay the MRV application fee unless so instructed by a consular officer.

REMARK: To avoid any unnecessary delay, please ensure that the photo submitted with the application meets the requirements. Please follow the photo guidelines found at the Photo Requirements Page.

Applications should be delivered to the Embassy by diplomatic courier a minimum of four working days prior to departure. A consular officer will review the application and determine whether the applicant qualifies for a diplomatic visa.

If the applicant qualifies for a diplomatic or official visa, the Embassy will waive the fingerprinting requirement and the visa application fee. The visa application fee is nonrefundable, even if paid in error. The Embassy processes the visa, which will be ready for pick-up at the diplomatic window on the following Monday or Wednesday during diplomatic window hours.

If the applicant does not qualify for a diplomatic or official visa, the Embassy will return the application to the applicant or courier. The applicant will be directed to fill out a DS-160 application in the correct visa class, then book a visa appointment through the online appointment booking system or call center. Such applicants must pay the visa application fee (unless they have a diplomatic passport) and bring the receipt to the Embassy on the day of the interview. Applicants must be able to provide, at the time of their visa interview, a diplomatic note attesting to their purpose of travel.

A3 and G5 visa applicants (Personal/Domestic employees of representatives of foreign governments) must first be registered with Department of State’s Office of Foreign Mission Management System (TOMIS) via the eGov system before applying for a visa.  For more information about registration, please contact

Treaty Trader (E-1) and Treaty Investor (E-2) visas are for citizens of countries with which the United States maintains treaties of commerce and navigation. Thailand is one of these countries. For a list of all treaty countries, click here.

To qualify for Treaty Trader (E-1) and Treaty Investor (E-2) visas applicants must be coming to the United States either to:

  • Engage in substantial trade, including trade in service or technology, in qualifying activities, which is principally between the United States and the treaty country; or
  • To develop and direct the operation of an enterprise in which the applicant has invested a substantial amount of capital.
  • To learn more about E2 visas, please click here

The spouse and unmarried children (under 21 years of age) of treaty traders, treaty investors, or employees of enterprises may receive dependent E visas in order to accompany or follow to join their spouse or parent. They are not required to have the same nationality as the principal applicant to obtain an E visa.

E visas permit the investor/trader and his or her family to live in the United States during the period of stay authorized by the Department of Homeland Security (DHS). E visas are nonimmigrant visas; consequently, visa holders are allowed to live in the United States only so long as the conditions under which the visa was granted remain valid. Holders of E visas must intend to depart the United States upon the termination of their E status. Dependents are not authorized to work in the U.S. unless they receive explicit authorization to do so from DHS-USCIS in the United States. Dependents of treaty traders/investors may apply for work authorization after their arrival in the United States.

How Long is Visa Processing?
Your E-visa application requires a lengthy review of up to four weeks. Therefore, we must receive your supporting documents at least 15 business days before your interview date. Failure to submit your documents in a timely manner will significantly delay your appointment time. If we do not receive your documents at least 15 business days prior to your interview date, your interview date will be rescheduled to at least three weeks after you submit your documents. Your interview date can be rescheduled up to 3 times. After that, you will have to repay the visa fee and restart the process from the beginning. WE STRONGLY RECOMMEND THAT YOU PREPARE ALL THE NECESSARY DOCUMENTS BEFORE YOU SCHEDULE AN APPOINTMENT.

How to Reapply

Applicants are ineligible under Section 221(g) of the INA because some document or information is missing. If you are ineligible under Section 221(g), we will give you a letter listing what is needed and explaining how to submit additional documentation. A new visa application fee is NOT required for 221(g) ineligibilities within one year

Ineligible under Section 214(b)
If an applicant is found ineligible under Section 214(b) of the INA, we recommend that he/she reapplies only after his/her current family, social, professional or economic circumstances have changed significantly and/or if there are important facts that were not presented at the initial interview.
