I just received my non-immigrant ED visa to learn Thai on 4th April and collected my new passport afer that, and I managed to transfer the stamps and multiple re-entry permit from the old passport to the new one. I am posting this because my langauge school couldn't really advise me on how to transfer the stamps. My school advised me not to collect my new passport until my NON-ED visa has been issued.
I am a Singapore passport holder, and I entered Thailand on a เธ.30 status (visa exempt for tourism for 30 days) and then extended my stay for 30 days on the basis of tourism. I then applied for an in-country NON-ED visa with the help of my language school. After getting my visa and collecting my passport, I went back to Chaeng Wattana to attempt to transfer the stamps. However, I was informed that since I entered visa-exempt (เธ.30), I had to go to Muang Thong Thani Counter K first to get the visa exempt stamps (including the extension based on tourism) transferred first and then return to Chaeng Wattana to get the NON-ED stamp and the re-entry permit transferred. At Chaeng Wattana, I went to counter C/C1 to transfer the NON-ED stamp (not including the visa, since it has already been stamped as used). The transfer of the re-entry permit was done at counter C2. The transfers were all completely free of charge. I was also told that to apply for an extension of stay based on studying Thai, I still require my old passport.
Documents submitted (for both Muang Thong Thani and Chaeng Wattana counter C/C1, unless otherwise stated):
- original old and new passports
- photocopy of TM.6 (I never submitted the original)
- original embassy letter (Muang Thong Thani took it, so Chaeng Wattana didn't need it)
- photocopies of the biodata page of both my old and new passports
- photocopy of my entry stamp (the red one given at immigration checkpoints, NOT the NON-ED in-country admitted stamp)
- photocopy of my extension stamp based on tourism
- photocopy of my NON-ED visa + stamps
- two transfer of stamps forms (one for MTT and the other for CW).
Counter C2 (re-entry permit counter) at Chaeng Wattana did not need any photocopies, just my old and new passports.
I also successfully exited Thailand at the Sadao land border crossing with Malaysia today (and successfully entered Malaysia). Might be good information for those considering going to Malaysia or doing a border/visa run by land. I flew from Bangkok to Hat Yai to get to the border. Requirements to enter Malaysia can be found at [members only]/
TLDR : Answer Summary
The process for transferring visa stamps from an old passport to a new one in Thailand involves visiting two specific immigration counters. The individual, who held a non-immigrant ED visa for studying Thai, shared their experience with the process after receiving their new passport. They initially entered Thailand on a visa-exempt basis and extended their stay for tourism. After successfully receiving the NON-ED visa, they were advised to first have their visa-exempt stamps transferred at Muang Thong Thani before completing the transfer of the NON-ED stamp and re-entry permit at Chaeng Wattana. The transfers were done free of charge, and it was noted that the individual still required their old passport for future extensions based on studying Thai. Additionally, they shared insights about crossing the land border into Malaysia, noting the updated entry requirements for travelers into Malaysia.
