Could someone confirm if this is OK or have I missed some details?
- I am graduating from University
- My last grade will be released by the end of September
- My ED-Visa extension is valid until October 12th
According to my multi source research and understanding, to continue my stay in Thailand I should get a letter from school stating the date of the end of my studies and bring it to immigration to cancel my stay permit. Immigration would give me time to stay until the date stated in the letter from school.
Next I would have to leave Thailand before or on the date stated in letter. I get a Thai tourist visa from another country or fly back in to get the visa exemption on arrival.
TLDR : Answer Summary
To extend your stay in Thailand after graduation on an ED-Visa, you'll need to obtain a letter from your university confirming the end date of your studies and present it to immigration. This will allow you to cancel your current stay permit and receive an extension until the date specified in the letter. Be aware that the immigration officer may stamp the date of your visit rather than the date in the letter, which could affect your stay. After that, you can apply for a Thai tourist visa from another country or re-enter Thailand under a visa exemption.
