Hi, I have a multiple entry tourist visa and entered Thailand from the UK in January. I have the date 20th March in my passport. I am on Koh Phangan...do I need to go to Koh Samui by 20th March (where they have an immigration office) or do I need to leave the country by 20th March please? Is there anything else I need to leave/re-enter - money? Will I get another 60 days to stay? My visa is valid until 5th June. Thanks
TLDR : Answer Summary
You have a multiple entry tourist visa and need to ensure proper handling of your stay. By 20th March, you should go to an immigration office for a possible extension of 30 days. After this extension, you will need to leave Thailand and re-enter to gain an additional 60 days of stay.
