American Citizen Services


The U.S. Embassy in Bangkok is one of the largest U.S. diplomatic missions in the world. Comprised of several dozen U.S. agencies and sections, the mission of the Embassy is to advance the interests of the United States and to serve and protect U.S. citizens in Thailand.

The U.S. Ambassador is the personal representative of the President of the United States and is the chief advocate of U.S. policy in Thailand. 

The Embassy analyzes and reports developments in Thailand that are of concern to the United States, and advances a broad range of U.S. policy initiatives. The Embassy promotes United States economic and commercial interests, the export of American agricultural and industrial products and services, and otherwise assists American business, workers and investors. The Embassy engages the government and a broad range of organizations and individuals in Thailand to promote shared values. Among others, these include individual freedom, human rights and democracy and the rule of law.

The Embassy urges all American citizens, even those visiting Thailand for a short time, to enroll with the Embassy’s Consular Section. In the event of an emergency, the Embassy will provide information and other critical assistance to American citizens. Enrollment is the only way to guarantee that the Embassy is aware of your presence in the country and is able to contact you and assist you in such circumstances.

American citizens may enroll online at The enrollment system allows you to enroll and update your contact information online at any time, making it easier for you to keep your information current. The site also provides you with up-to-date travel information customized to your unique travel agenda and itinerary. The data you provide is secured behind Department of State firewalls, accessed only by cleared personnel in Embassies, Consulates, and the Department of State, and releasable only under the provisions of the Privacy Act.

The Embassy’s primary means of communication with American citizens in Thailand during an emergency is our warden system. The warden system consists of American citizens who volunteer to disseminate information passed on from time to time by the Embassy to other American citizens in the country. We also distribute this information directly via e-mail to any American citizen who asks to be included in our warden notification network by enrolling with us online. To see recent messages (called Warden Messages) sent under the warden system, please visit 

Travel Alerts

Travel Alerts are issued to disseminate information about short-term conditions, generally within a particular country, that pose imminent risks to the security of U.S. citizens. Natural disasters, terrorist attacks, coups, anniversaries of terrorist events, election-related demonstrations or violence, and high-profile events such as international conferences or regional sports events are examples of conditions that might generate a Travel Alert.

Travel Warnings

Travel Warnings are issued to describe long-term, protracted conditions that make a country dangerous or unstable. A Travel Warning is also issued when the U.S. Government’s ability to assist American citizens is constrained due to the closure of an embassy or consulate or because of a drawdown of its staff. The countries that meet these criteria are listed at:
