Can I apply for a 30-day extension after my 45-day visa exempt entry using the eExtension website in Thailand?

here's a post about the eExtension system

You apply for the eExtension HERE

First off there is no 45 day visa on arrival 😮 so if you're from Italy, showed up here and were stamped in free for 45 days that's a visa exempt entry NOT a visa on arrival, NOT a visa at all, just a free entry stamp.

In answer to your question, Yes, you can use the online eExtension process,

BUT

you still go to the immigration office, you still turn in your paperwork and you still queue up to get the extension stamp in.

It's also NOT a free service and you pay more than the 1900baht you pay for the extension to use the eService.

Just go to your immigration office and get the 30 day extension for 1900baht like every one does 🙂 there's not really a lot of benefit using the eSystem at this time..
