Yes, it is possible to open a bank account in Thailand as a foreigner with a DTV (Digital Nomad Visa), but it depends on the specific bank and their policies. Generally, Thai banks require foreigners to present the following:

A valid passport with the relevant visa.

A work or residency permit (the DTV visa may meet this requirement).

Proof of address in Thailand (often a rental agreement or proof of residence).

Some banks may also require a recommendation letter from your employer or the Thai authorities.

It’s a good idea to contact the specific bank where you want to open an account to get detailed requirements. Major banks in Thailand, such as Bangkok Bank, SCB (Siam Commercial Bank), and Kasikorn Bank, often have flexible rules for foreigners.
