I work in the Middle East and have never before had to spend more that 90 days in Thailand. At present my 90 day allowance will expire on the 17th August.

I received a mail today stating I will return to work next week but have not been given an exact date. Just checking if it will be an issue if the job is cancelled or delayed and I go and make a land crossing at Chong Mek

Would I just pay a fine for a few extra days, or do I need to exit Thailand on the 17th to avoid any problems.

Would it be possible to go to Thai immigration and get a 1 month extension ?

If you married to a Thai you can apply for a 60 day extension to your wife at an immigration office for a fee of 1900 baht. If not the longest extension you can get is 7 days to leave the country.

The over stay fine is 500 baht a day. It only takes 3 days of over stay to pay the fee for a Lao visa.on arrival. Best to just go out for a new entry.

Joe many thanks for the fast reply, regarding the 7 day extension do you have the cost for that one.

Regarding the overstay fine can that be done at a land crossing or is this only done at the Airport prior to departure. I have never been on overstay before

All extensions cost 1900 baht.

You could pay the overstay fine at the border or at the airport.

All extensions of stay cost 1900 Bht including the 7 day extension.
