Hi. I have a Single Entry Non B visa with work permit. Shortly after I received the visa and work permit, I left the Kingdom, but I did get a re-entry permit. I arrived back in Thailand on 30 December. So I need to do my first 90 day reporting within the next few days. I am living in Chiang Mai. What should I take with me to Immigration?
TLDR : Answer Summary
If you are in Chiang Mai and need to do your first 90-day reporting after returning to Thailand with a Single Entry Non-B visa and work permit, you should bring your passport, the re-entry permit, your work permit, and any documents that verify your residence in Thailand, such as a rental agreement or utility bill.
