• Check the current validity of your passport and the availability of blank visa pages
  
  All travelers will need a valid passport for their travels to Bangladesh. Also, the passport must contain un-used visa pages for the visa to be issued. We recommend traveling with at least 6 months of remaining validity on your passport at all times. VisaHQ can assist U.S. citizens with a full range of expedited passport services, including new passport application and passport renewal. We recommend that you have at least two free pages in Visas section of your passport before any international travel.
   
• Contact the nearest embassy or consulate of Bangladesh
  
  Take advantage of our extensive embassy and consular database to find the nearest one. Upon contacting the embassy confirm the required documents, the time it takes to process the visa and whether the consulate accepts applications by mail.
