Can I apply for a 30-day visa extension in Thailand after overstaying for 2 days?

You book hotel again meaning today or asap. Thwn ask the hotel staff to register the TM30 for you for immigration purposes. Ask them for a copy of the TM30 registration. Tell them you are going to the immigration after you boom the hotel. You have to tell them because not all hotels register the TM 30 if you dont tell them that you need it. So better, when you go to the hotel, ask them you need TM30 registration. If they say they dont do it, then m9ve to another hotel that does. It is their responsibility, but many small guesthouses dont do it. So better go to a hotel that does.

Like Tod has mentioned, go and try to apply for the extension. Worse case scenario is you have to pay a fine for not having the TM30. The fine is 800฿ and up. I paid 800฿ last month but have heard of others paying more.

You’ll end up paying that for a hotel for the night.

1900฿ for the extension, the additional 800฿ for the TM30 fine and 500฿ per day for overstay.

Please note, if you’re going to the immigration office today, be prepared to be there all day, as Fridays and Mondays are the busiest times to go.

Good luck.

Doesn't have anything to do with your entry stamp being expired the online TM30 system can only access data for 15 days. You needed to print it out right after it was filed 😕

You'll have to pay 500baht a day for the overstay and the extension will start the date your current stamp expired

You could check into a hotel for one day, have them file a TM30 then go apply

BUT

Go try and you'll either get it or you won't.

It's not like you have a lot of choice really 😕
