I went to Bahrain yesterday (23 August) around 12 pm for a tournament. I am a lecturer working in a university so my iqma profession said (Muhaadir). Based on that i had to go into the passports office myself before exiting the saudi passports. He saw the profession and let me go. On bahrain side i also had to go to the passports office again and there they asked about my profession and what i am going there for. After that he let me go. So i guess its profession based i guess.
