Question about extension of stay on ED visa:
My extension of stay (on an ED visa) is done every 3 months. What should I do if I plan to be outside of Thailand and it conflicts with the date for applying for an extension of stay?
I believe the extension can be done 30 days in advance of the expiration of the current extension. Should I absolutely plan to be in Thailand during the time of the extension (30 days or less before the application for extension)? If am not in Thailand during the period for extension, does the automatically invalidate the visa and any possibility for extension?
TLDR : Answer Summary
If you need to leave Thailand and are unable to apply for your ED visa extension on time, you must cancel your current extension before departure with a letter from your school. The ED visa is meant for study in Thailand and typically requires you to apply for the extension within the last 30-45 days of your current stay. If you leave without properly managing your extension, you could risk overstaying, requiring you to start the visa process over upon your return. It is advisable to discuss your plans with your school and obtain necessary documentation to avoid complications.
