Extend 30 day stamp from airport

[colinthailand20005]

I would like to extend my 30 day stamp upon arrival.

My current permission to stay finishes on the 3rd September, I need to stay until the 8th September.

When can I go to the immigration office and extend 7 days?

Do they always add the 7 days as an addition to my current permission to stay?

My nationality is British.

Thanks for your replies.

If you have a ticket out of Thailand it should be no problem You should go on the last day as some offices start the 7 days on the day that you apply. The cost is 1900 baht and you must complete a TM 7 form.

I have a plane ticket for the 8th September, and could really do with getting my extension sorted out in the next couple of days.

But if I must wait so be it.

You can go for the 7 days anytime.

It will be effective as from the end of your current permission to stay.

You will need 1900bht , a passport photo and copies of your passport, departure card and your "permission to stay" stamp.

It is not an official extension, so you might be told to come back at a latter time if you try it now.

You can go early.

Most offices now start the 7 days from the existing permitted to stay date.

Since you have a ticket out they will make it at a minimum to the 8th.
