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.
