it used to be. I’ve had 4 or 5 off them in the past. At 3k a go it was a good money spinner too, not sure why they stopped. Especially with bkk immigration insisting on a 90day report before they’ll issue a CoR - for people that travel a lot it can make getting a license/buying a vehicle here challenging. The embassy offering it was a good solution.
And I should add that immigration (Bkk) doesn’t seem to care about the date of the TM30. So I’ve done one a week or more after I arrived. For 90 day report they just want to see A TM30 on file.
