Will a hotel report my overstay to immigration in Thailand?

Overstaying your date in your passport is breaking the law.

Many times on here people ask is it ok to overstay - 1, 2, 5 days etc. The fine at the immigration exit desk is 500 baht per day of overstay. Some immigration officers will waive the fine if it is only 1 day, but you’ll still get a red stamp in your passport.

HoweVer if you are stopped inside the country for any reason - like at a police check point - even on your way to airport or border crossing then be prepared for a whole lot of trouble.

The police may arrest you as you have broken the law. If they do you’ll be fined in court and then sent to the nearest Immigration Detention Centre, where you will be kept until you buy a one way ticket back to your home country. If you don’t have the funds for that you will be kept there until you find some means of raising those funds. Once you have your ticket, you will be deported and blacklisted from entering the country for up to 5 years.

Sounds dramatic but it sometimes happens. 500 baht a day sounds cheaper than 1900 baht at a local immigration office but in the overall scheme of things it is never wise to overstay.

Stephen gave the best advice, go to immigration and apply for an extension, it will get denied and you'll get an additional 7 days.

What visa are you on now ?

Sound very dodgy for them to issue an ED visa if visa in your passport has expired.

They'll be knocking on your door with cuffs the minute the clock ticks past midnight.

Did you ask the school who will pay the overstay fine?

If you think you are going to be on an overstay you should go to immigration before it happens. No need to intentionally overstay.

Go to immigration and request an extension that they will deny but still give you a 7 day extension to leave Thailand. 1900 baht but no overstay repercussions.

Yes

How are you on overstay?
