Rather foolishly, the slip from the TM30 I did in-person at Chaeng Wattana has been lost. I'm currently renewing my passport, which should arrive in 4 weeks. Can I simply re-do my TM30 without penalty, despite not having stayed anywhere else? Should I wait until my new passport arrives, as presumably I'd need to update that information anyway, or should I do it before then as I don't have the old TM30 receipt anymore? Thanks. Yes, I'm kicking myself over this.
TLDR : Answer Summary
The user is inquiring about re-submitting the TM30 form after losing the original receipt while waiting for a new passport. Comments from the community suggest that it's acceptable to submit the TM30 again to obtain a new receipt even without proof of staying elsewhere, and that once the new passport is received, the TM30 should be updated accordingly.
