^^ This was at Dhaka Airport. It was for their internal database, where they in put relevant information. You know you see them typing something in their computer and then take your picture with the webcam and then stamp the outgoing seal in the passport ?
The officer wasn't sure under what category he would record my wife's data as her 'profession' in the passport is student but she was traveling with me and I had business visa. So he wasn't sure whether to put her under business or tourist visa.
He was trying to find out where we were travelling to and wasn't sure what Schengen meant and unfortunately, even his learned colleague graciously informed him that it is an European country !!
