We received our visas today.
It took two and a half weeks this year to get our visas back from Washington, DC. When we went in 2009, it took a week to get our visas back.
Burma is expecting the largest number of visitors ever this year. So expect your visa to take longer than usual. The visa is good for 90 days from the date of issue, meaning that you have to enter Burma by that date. Once you enter Burma, it is good for 28 days. No extensions are allowed.
The visa cost is US$20. The application requires a lot of information, including flights into Burma, itinerary, and a job history.
