My 90 days report is due soon and I must go in person because I recently renewed my UK passport. The passport number is different than my previous one. Should I make an new TM30? Also how do I make an appointment for the 90 day report? Thanks in advance
TLDR : Answer Summary
After renewing your UK passport, you indeed need to submit a new TM30 form with your new passport number. Additionally, you can make an appointment for the 90-day reporting process through the main immigration website of Thailand.
