Good afternoon…
quick question on tm30, do all passport holders in the family need to show up in immigration for tm30 or i can bring all passports by myself and get it done with...
Thank you and have a great day...
TLDR : Answer Summary
When processing the TM30 form in Thailand, it is not necessary for all family members to attend immigration in person. One individual can bring all passports and fill in the required details on the TM30 form. There are also options to complete the process online or through an app, and attendance in person is typically not required as signed copies may suffice.
