What should I do if my 30-day visa is about to expire and I want to stay in Thailand longer?

Many years ago I needed a 2 day extension similar to you. Went to immigration for an extra 30 days and was told no need, just overstay the 2 days.

No fine but you do get the dreaded red pen in your passport.

Of coarse all immigration offices are different so it's a roll of the dice.

Even a few hours is an overstay. 1900 baht buys you 30 more days!

If you don’t like to waste time at immigration, just go to an agent. For little money they will provide you with a 30 days extension. Before I had my NON-O visa I did it many times. My agent charged me 500 THB for this support. I handed over my passport, picture in the morning and afternoon same day I had my extension stamped. Don’t take the risk of overstay.

It definitely might affect any future plan of applying for a longer term visa. Otherwise spending a few days in a Thai prison can’t be all that bad, can it?

Quit trying to game the system

It's their country. Break the rules and suffer the consequences. Don't listen to other 'advice' on fb. If you are arrested and held in immigration prior to being deported and banned, the wi fi in the Bangkok Hilton is probably not too good if you want further advice then.

Just extend for the 1900 bht 🤷‍♀️. Then at the end of that, you could leave and fly back in to do the same again? Totalling 120 days 😊

Do a one day broader run get extra one month in Thailand

I paid 500 baht for each day I over stayed in at airport no problem I done it twice one or two days ok

Pay 500 baht fine for each day you stay I've done it a couple of times

It might affect you from getting certain long term visas in the future.

Never overstay get a visa / visa extension.

All the advice you have been given about getting the 30 day extension to avoid an overstay is correct.

In case you don't know the first day you arrive - even if it's after 11 pm - is day one (not day 0) so the 30 days is up on what you may otherwise count as day 29 of your holiday.

Just be aware people have been arrested ,yes ARRESTED for being one day over ,, you can go get 30 day extension for 1900 baht

Jeez.....really you are asking is it ok to break immigration rules . Why not just follow them and avoid any issue ?

But if you do overstay . Just don't get caught by police because your consequences would be a fine and a ban of up to 5 yrs . So I think a 1900baht extension pays off

Get the extention, you dont want to be on overstay!

If you go the 2nd it's 1500 baht fine. The 3rd it's 2000 baht fine. An extension is 1900 baht. Up to you really

Pay for an extension especially if you want to have another visa in the future

You will be fined 500 bhat per day for overstay .. it’s no problem and no issue , unfortunately years ago I did it many times , 2-3 , and a couple of times 5 days … infact once they told me I’d overstayed by 2 days , and never even fined me ! .. that all was years ago , but my understanding ( I live here now ) is that they are quite happy , as long as your not taking the pi** ..

Go and get a 30 day extension

Anecdotal comment: I had a similar situation at the end of my last trip a couple of days would've made things much more convenient for my travel but it felt like such a hassle to get an extension for three days. I posted to get a sense of how big a deal a short overstay would be. The answers were super aggressive - you would think I asked about child trafficking. I decided to just leave early. Anyway I am a effing idiot and had miscounted the days and so I thought I was leaving my last day but had actually overstayed 3 days even though I picked that date to avoid the overstay. Getting old and losing cognitive function sucks. I was horrified, but the IO insisted it would not be an issue when I returned and paying my fine was all the punishment there would be and not to worry and everything was going to be fine.

Now I haven't gotten back yet - one more week... And he wouldn't be the first Thai public servant to give me false information and I could get turned away at the desk... But he was super calm and very reassuring so... We will see what happens.

There is a fine of 500 baht for each day you are over your permission to stay, and you will get an overstay stamp in your passport. But more importantly if you are found to be on overstay other than at the airport when leaving you can be arrested, taken to the immigration detention centre and deported. It's really not worth the risk, go and get an extension.

Good luck 🍀

Following the law seems excessive?

If you have any interaction with the police on even one day overstay, you'll be arrested, held in immigration detention, processed, deported and banned from Thailand for 5 years.

If you make it to the airport you'll be fined 500₿ per day for each day of overstay and receive an overstay stamp in your passport which could cause issues entering Thailand, or even other countries, in the future. Why not get the extension which will cost about the same as your fine for overstating and also avoid any potential repercussions.

Seems excessive to maintain a valid visa in a foreign country? 🫣
