You must produce a company registration (outside Thailand) with your name as the owner or director, as well as a stamp from your country's Ministry of Foreign Affairs. Then, using the bank stamp (which must be in English), demonstrate the company's bank account on all transactions for the previous 3 to 6 months.

Otherwise, you will need a confirmation letter from the company stating how much you earn, whether you may work remotely, and when you started working. Also, include your monthly salary slips and your most recent personal tax submission.

Furthermore, you must show your personal bank account with 500,000 baht in your name (regardless of currency).
