In concordance with the country that has released your passport, transit visas may be necessary for any given connection in your route.
Please note that you are in charge of all the documents that may be needed for your trip.
If there is a need for transfer from one airport to another, with baggage that needs to be carried and re-checked, at a foreign airport most of the time airport transit visas are required
Most of the time airport transit visas are needed when travelers have to transfer from one terminal to another in a foreign airport, when baggage needs to be claimed then rechecked in an overseas airport, or if passengers split their international itinerary into several separate bookings.
Contrary to expectations, sometimes an entry visa may be required even if you only need to leave the arrivals terminal to access a different one within the same airport. Please, thoroughly check all the visa requirements for all the countries in your itineraries.
If you are not sure whether you need a transit or entry visa for any of the connections of your route, please contact the respective country’s embassy, consulate, or, otherwise, reach out to the appropriate immigration authority of that country.
