For future visitors to Myanmar-
Here is the OFFICIAL government website.
You will need to fill out the forms properly (as information appears on your passport), download a photograph, and pay the fee by credit card (US$50). It normally takes less than 24 hours for your application confirmation, and you will get your printable file, once the aplication is confirmed and processed, a day or two later. Print that out and have it with you when you present your passport at immigration upon entering Myanmar.
