Bangladesh tourist Visa is a simple one as it’s an on arrival visa process. For people who don’t like to stand in a queue and want to get the visa beforehand then this is the small procedure which should be followed to get the Visa.
The visa processing fee is to be submitted along with the file. The fee can be paid in cash or in the form of demand draft. So do take it along. Basically, it's not the Visa fee but a service fee is charged for the processing.
Three passport size recent photographs are required along. The photograph should not be more than six months old. The photograph should be clear enough that it shows from your hairstyle to chin. The eighty percent of the space of the photo should be covered with the face. Do not wear a hat or any kind of glasses when you get the picture clicked. The photo should be 45mm into 35 mm.
If you are visiting someone specific in Bangladesh then a letter from the person is a must.
Letter from your own company
If you are on job then letter from your own company approving you leave or if you have your own business then details about it. This serves as a proof that you will come back.
