Bangladesh - Visa on Arrival
Not many travellers know about the "visa on arrival" facility at Dhaka Airport - and those who do have also heard many confusion details about who it applies to. In the past, it has also been withdrawn and re-instated on more than one occasion.
It now is permanently available to passport holders from a list of countries that includes EU, USA, Australia, Japan. Upon arrival at DAC, you approach the leftmost immigration desk to apply, then pay $50 at the Somali Bank desk, go back to the immigration officer who then stamps a landing permit valid for 30 days (might vary according to your nationality) into your passport.
The advantage is not only the convenience, but frequent travellers will appreciate that it also avoids the usual full-page visa stamp they would otherwise get from an embassy or consulate. The landing permit is the size of the usual immigration entry stamp.
