U.S. Security Message: Bangkok – The U.S. Embassy in Bangkok recommends that U.S. citizens reconsider any non-essential travel to Thailand, particularly Bangkok, due to ongoing political and social unrest and restrictions on internal movements, including an indefinite nighttime curfew. U.S. citizens are cautioned that even demonstrations that are meant to be peaceful can turn confrontational and escalate into violence. You should avoid protest sites, demonstrations, and large gatherings. Be alert and aware of your surroundings and pay attention to local news media reports. Consider using public transportation.
