Hi,
I entered Thailand with a 90 day visa almost 3 months ago. Originally I planned to leave before 90 days are over. Unfortunately I have a medical issue and need to stay about a month after 90 days. My case is a bit different because I entered Thailand with a foreign passport. However I also have a Thai passport (but didn't use it for entering). What's the proper and simplest way to do this? I'm hesitating between these two:
(1) Leave Thailand before 90 days is over as originally planned to the close neighboring countries (Malaysia, Lao, etc) for a few hours and re-enter Thailand using Thai passport.
(2) Try to apply for a 30 day visa while staying in Thailand and ask for the start date as the end date of the 90 day visa.
I think #2 is less hassle but not sure if it's doable. Please share your thoughts. Thank you.
