When can I get my 30 day exemption extension? I arrived on March 25th. I am in Chiang Mai now. I’m eager to have it completed. If I go tomorrow, will the extension start on April 24 (the first day after my 30 days visa exempt)?
TLDR : Answer Summary
You can apply for your 30-day visa exemption extension as soon as you're eligible, which typically means you can go to the immigration office anytime before your current exemption expires. If you apply tomorrow, your extension will start from the day you apply, which would mean it would start from April 24, following the expiration of your original 30-day visa exemption.
