Transit guidance should begin with the route — not a generic checklist.
A traveller changing flights without entering Bangladesh may face a different situation from someone who needs to pass immigration, collect baggage, change airports or spend time in Bangladesh before the onward journey. Nationality and current immigration rules can also affect the requirement.
For that reason, the first step is to understand the complete route. If an application is required, the form and supporting papers should clearly show the arrival, intended stay or connection, onward departure and final destination.
Supporting information that may matter
Depending on current official requirements, useful evidence can include the passport, online application printout, photographs, confirmed or planned onward itinerary, destination-country entry permission where applicable, and an explanation of why entry into Bangladesh is needed during the connection.
