How can I extend my stay in Thailand if I'm facing a 3-day overstay?

I was told by my legal team that if I went to the airport and told them I would have a 2 day overstay they would fine me without consequence. As it happens I had to go to Malaysia so got the 60 day extension. I was in process of getting retirement visa and I took my docs with me but were not required at BKK

so you were going to leave Monday knowing that was a 3 day overstay, am I right? Now on Saturday you decided you want to stay longer. Go to Immigration Monday. Pay 3x 500 baht for the overstay and 1x 1,900 baht for the 30 day extension. Take it in cash

Ring around there will be a mini van somewhere with space to take you to Cambodia and bounce back for 60 stamp

Do sweat it . Small fine, no stamp for over stay

I would try and do a border run overstay is never good but you can extend plus the fine you probably have to go in your own or first thing in the morning

If near airport fly Vientiane get 60 days on return

Do a border run get 60 days

You really left it late due a boder run today if you can and your sound to return for 30 days.

Changing your flight may be the hardest part....

How far in advance can do a border run I'm going be 3 days over myself unless do a border run just don't want be staying around Pattaya forever

Or you could do a border hop

All could have been avoided had the OP been paying attention.....

Assuming you entered Thailand as a tourist and received a 60 day entry stamp, and you still have not used your 30 day extension, then yes you can still apply for the extension on Monday. You will need to have 1500 baht for potential overstay fine (500 baht per day), and you will still receive an overstay stamp in your passport. But they will still process your application and backdate your extension to when your original stamp ended, so you would not receive a full 30 days from your application date, but would still receive a full 30 days from when your previous entry ended.

Please be aware if you have any interaction with the police, like a random checkpoint, or any such thing, there is a potential for you to be arrested, sent to immigration holding, deported and banned from Thailand. This is a risk for anyone who goes on overstay so it's not something to be taken lightly. So don't take any unnecessary risks over the weekend.
