Can a foreigner marry a Thai woman?
In short
Yes. A foreigner can legally marry a Thai woman with no restriction based on nationality, as long as they meet Thailand's civil registry requirements, including an affirmation of freedom to marry issued by their embassy. Marriage can also open the door to a category O marriage-based visa.
More context
Marriage between a foreigner and a Thai national is fully legal in Thailand and doesn't depend on the foreigner's country of origin. The process happens at the district office (amphur) and involves presenting an affirmation of freedom to marry issued by the foreigner's embassy in Thailand, along with the usual identity documents for both spouses. The traditional Buddhist ceremony, with or without an added Western celebration, doesn't replace this legal registration — they're two separate processes. Once registered, the marriage opens the door to a category O marriage-based visa, subject to income or savings requirements and annual renewal.
