Hello ๐ How many days after arriving in Thailand (without visa) can you apply for 30 days extention? And will the extension be added to your first 30 days or on the day you apply for it? (Austrian Passport holder). Thank you in advance!
TLDR : Answer Summary
You can apply for a 30-day extension soon after your arrival in Thailand, often as soon as the next day. The extension is added to your initial 30 days, thus prolonging your stay from the date you entered. It's also advised to check with your local Thai immigration office for specific application dates and be aware of the TM30 requirement when applying.
