You have to ask Kasikorn for the document of the international transfer every month and that is for free. They can go back for 3 months only. If you wait for 1 year then you will have to pay 6000 bht. Please get the information at the bank yourself .😉
when I traveled to Thailand in the early 80s and wanted to stay more then 2 weeks I had to go to the Thai Embassy to get a visa. Same for the Philippines and most other countries.
