Went to CW today to get my stamps transfered to my new passport. While there I asked if it was necessary to file a new TM30. The IO said that as long as I haven’t changed address, there was NO need to file a new TM30.
TLDR : Answer Summary
The individual reported that while transferring stamps to a new passport at the Thai immigration office, they were informed that a new TM30 form is not required if there has been no change of address. However, it is advised to confirm this with the local immigration office, as practices may vary.
