Build the file around the real reason for your visit.
A private visit should not be documented as a business trip simply because an invitation exists, and a family stay should not be presented as hotel-based tourism if the applicant will actually stay with a host. The application form, Bangladesh address, intended stay and supporting papers should tell the same story.
The Bangladesh Online MRV Portal currently directs applicants to complete the form online, print it and submit the printed application with the required supporting documents through the relevant official route. Current mission requirements take priority over general guidance.
Information commonly worth preparing
Depending on the current visa category and mission checklist, a visit file may need passport and photograph documents, the printed online form, Indian identity or profession evidence, Bangladesh accommodation details, and host identity or invitation evidence where applicable.
Do not add unrelated documents merely to make the file look larger. A concise, consistent application is easier to understand than a bundle of papers that describe different travel purposes.
