Hi, I am a dual national holding Pakistani and British passports. I have Saudi residence (Iqama) card made on my Pakistani passport. Now I want to visit UK for a short trip. I will obtain exit/ entry visa on my Pakistani passport. My question is whether airline and Saudi immigration staff will allow me to travel to UK as I have valid British passport?? or there is a need to obtain UK visa on my Pakistani passport? I am asking this question because Saudi Arabia doesn't allow dual nationality and may not recognize my British passport as a valid document to travel there.
