Arrived on a 3 month Non Immigrant O visa ( retired) and now want to extend. Immigration want the TM6 DTAC form as a requirement which has long???? I don't have it anymore and can't get a copy.

What do I do.

Thanks
Answer summary
The poster has a Non-Immigrant O visa which they need to extend but has lost the TM6 DTAC form required by immigration. They are seeking advice on how to proceed without the form. The community suggests multiple options, including checking emails for the DTAC number, considering the possibility they might need their TM30 instead, and even the option of taking a re-entry permit and leaving Thailand briefly to obtain a new TDAC. Overall, the conversation is focused on practical next steps for dealing with Thai immigration requirements.

buy a re-entry permit for your 90-days stay permit on the Non-Imm-O visa, for 1000 THB. Exit Thailand, fill out a new TDAC and submit it, receive an email with the new TDAC, re-enter Thailand, and there you are. Your Non-Imm-O will still be valid and you will have a TDAC to show

Oo Jig The TM7 paper is asking for your TM6 number. Ignore it. If you came in by air you don’t have one. Leave it blank.

They are NOT asking for a TDAC number.
