Hi I am a Thai holding Thai ordinary passport. I will take a flight of biman from nepal to Bkk and have a transit for 1 day about 24 hours period (1 aftertoon, a night and 1 morning). Whether I needs the VISA in case i am within airport. And if I would like to go outside the airport, can I get transit visa at Dhaka airport. Is there any counter for transit VISA there?
