Hello, I entered Thailand by air and obtained a 30-day visa (French passport). Am I eligible for one or two extensions? If I am only eligible for one extension, can I do a visa run without any issues? Thank you for your kind responses.
TLDR : Answer Summary
You can extend your 30-day visa once at the local immigration office. After that, you must leave Thailand. A visa run to a neighboring country should not pose any issues unless there are specific restrictions based on your travel history.
