Fill out the application form for renewal of passport. These forms can be picked up at a Bangladeshi embassy, a local government building (such as a post office) or online.
Take your completed passport form as well as your current passport to the Bangladeshi embassy or the government building where you receive the application form. You will not need to take or bring a new passport photograph.
Pay for the allotted amount of years you want your passport to be good for. Rates vary from $22 for a one year extension to $165 for five-year passport as of September 2009.
Decide how soon you want the passport. Paying the ordinary fee will result in you receiving the passport the next day (the passport must be picked up). If you want to pick up the passport the same day, you will need to select the urgent service type ($33 for one year).
