How can I report my 90-day stay in Thailand by mail and confirm receipt?

To do a 90 day report by mail in Bangkok you need to postmark the envelope 14 days before the due date, and include a stamped self addressed envelope to get the receipt mailed back

Include the following in the packet:

Filled out TM47

previous 90 day report receipt

copies of

data page of your passport

visa/extension

most recent entry stamp

(They used to require TM6, but might be good to include a copy of your TDAC if you have it)

TM30 receipt

Mail it here;

Immigration Office Division 1

Chalermprakiat Government Complex

120 Moo 3 Chaengwattana Road Soi 7

Thungsonghong, Laksi Bangkok

I think it's better if you do it yourself, as sometimes postal deliveries can be inaccurate and we can't track how many days it will take to get it back.

Or if you'd like to use it instead, let us know, we can make it happen.

When you enter Thailand, its counted as first report, which can only be done in person at immigration. Only if you extend, a dtv holder can do it online or mail. Based on what you asked I think its your first, so you need to go immigration. If Im wrong and you already did 1 and extended dtv, forget my comment :)

If you want to do it by post send via EMS at least 15 days in advance of the due date and include a stamped envelope for the receipt to be sent to you
