About 2 weeks before my flight from germany to Thailand i registered for the 6 Month Multiple Entry VISA in the Thai Consulate in Munich.
Of course I received the approved Multiple Entry VISA 4 days after my flight date. So I entered Thailand via BKK on a 30 day entry stamp.
I extended the 30 day entry stamp for another 30 days in Chiang Mai immigration.
Now my question: Can I still use my approved Multiple entry VISA (that was approved 4 days to late *lol*) on my next border run when I fly for example from BKK to Vietnam and back to BKK.
TLDR : Answer Summary
The user inquired about the use of their approved Multiple Entry Visa (METV) for entry into Thailand after entering the country on a 30-day entry stamp. According to comments from the community, the user can indeed use the METV as long as it is valid, regardless of its approval date being after their arrival.
