There is a lot of new possibilities for the visa, it is quite confusing. The BEST and more simple, is to get your visa in a Myanmar Embassy before coming.
There is a lot of problem with the Visa on arrival (business or tourist) because people do not respect the procedure. Immigration officers are trying to help BUT the best is to respect the conditions and requirements to get the visa on arrival.
You must request to the Myanmar Embassy in your own country if you have one ,please send also your passport along with the request and the 2 forms.
Questions, issues or concerns? I'd love to help you!
