Do I need to apply for a visa extension a few days before it expires in Thailand?

Glad it worked out, (y)

, just so you know you need to use an address IN the area where the immigration office is located to get an extension. Meaning you can't use the Pattaya immigration office to get an extension using a bangkok address.

Also as people pointed out in Jomtien if you're staying at a private residence your land lord OR you needed to file a TM.30 form within 24 hours of you taking up residence there. OR you're gonna get a 1600baht fine for failure to have done it.

I'd say just go get your extension in Bangkok out at the government complex on Chaengwattana Road. The immigration office there doesn't care at all if you or your land lord ever filed a TM.30 form or not.

Always best to visit early, instead of the last day, IN CASE there are any problems with your documents you have time to resubmit without incurring any overstay penalty...good luck!

Go now...no need to wait.

Just go before it expires. They will add the 30 days extension to the original expiry date. So you will not miss out on any days from the extension. Also it's 1900 Baht.

If you go late, you would have to pay an overstay fine of 500B/day.
