Thank you. I have actually found one website that has quite detailed information about Visa runs to Burma through Mae Sai, with a map and evrything:
http://www.itisnet.com/english/asia/Tha ... maesai.htm
The only problem is there seems to be some confusion about where I would get the exit stamp from the Thai Immigration.
At one place the author says: "To get the exit stamp, you cannot get it on border. You must come here (marked I on the map). Thai Immigration is on the main road,
half way from the bus station to the town."
But later on the author says however: "If you want to renew your Thai visa,
go straight to the border and get the exit stamp at the Thai immigaration. Then go to Myanmar immigration and pay for the visa $5 or 250B. Leave your passport to Myanmar immigration and receive the document for their holding your passport. You can get you passport back when you leave and you can get new Thai visa for 30 days when you re-enter Thailand."
So my question is: Is the Thai Immigration located by the border in front of the bridge
or about 3 km from the bus station (marked I in the map)? Of course I will find out one way or another but it is good to know beforehand if I take the Tuk Tuk from the bus station straight to the border for my exit stamp or stop about halfway from the bus station to the border? Also: Should I bring photos for the Burma Immigration or do they only want to use the ones they take themselves?
