The Royal Thai Consulate General, Los Angeles has been receiving inquiries from Thai citizens residing in the United States regarding the guideline for Thai citizens who hold both Thai passport and U.S. passport. The question was asked specifically in the event that Thai citizens travel to and from Thailand, which passport should be used as travel identification document.

Please be advised that Thai immigration officers will inspect and put immigration stamps only on one passport book which was used at arrival and departure inspection booths. Pursuant to Thailand’s Nationality Act, B.E 2508, Thailand does not recognize dual citizenship. Therefore, if a person uses his or her Thai passport book when arriving Thailand, he or she has to use the same Thai passport book when departing Thailand. Vice versa, if a person uses his or her U.S. passport book when arriving Thailand, he or she must use the same U.S. passport book when departing Thailand in order to receive appropriate immigration stamps.

Please be advised and follow the above guideline.
