Any help is appreciated.
I applied for an e-visa but it still hasnt come, so i'll have to come on a 30 day exempt and extend for 30 days.
What do i do if i then finally recieve my e-visa once i have arrived in Thailand? Is it completely invalid seeing as it arrived once in the country?
TLDR : Answer Summary
If you receive your e-visa after entering Thailand on a 30-day visa exemption, it is not invalid; however, you will need to leave Thailand and re-enter to activate it. The e-visa is typically valid for 90 days from the issue date. While in Thailand under the visa exemption, you can extend your stay for an additional 30 days. When entering Thailand with a visa exemption, you may need to show proof of hotel booking and sufficient funds, although immigration rarely checks these documents. As of recent updates, the requirement for filling out the TM6 arrival card has been temporarily suspended.
