You can pay an extra 4000 baht for multiple entry otherwise you have to get a re- entry permit before every departure 1500 each time . Some people have forgot this making the visa invalid when they return and they have to start again đŸ¤”
My friend got one from uk embassy in 5 days.The process and requirement was very easy. Maybe its neighbouring countries to Thailand that are making the requirement’s more difficult. Maybe they want to attract new people to Thailand rather than people who are all ready in thailand and choosing the DTV to stay here and/or because its a better visa option than they all ready have. đŸ¤”
