Salam,
Tried to leave KSA from causeway for the purpose of exit re entry to reset my wife duration of stay. There are many posts suggesting nothing is required and you can get visa on arrival at Bahrain Passport. This is not right and may be they will issue on arrival visa if by LUCK or CHANCE you get exit from KSA Passports.
Saudi Passports will not let you leave if you dnt have Bahrain Visa for your family. For iqama holders it is not an issue but for Multiple Entry Visit Visa family members should have a Bahrain visa to get exit stamp.
I am not sure which Bahrain visa will work in order to get exit on KSA Passports and which one will be accepted when you reach Bahrain Passports.
If you have any information which Bahrain visa will be good to get and exit from KSA Passports @ Causeway please let us know.
And for those who are planning to do same which I did Today, Please take Bahrain Visa for your family otherwise it will headache to even return back. They used my re entry also Now I have to get another to try leaving again
I will keep this post updated as I will try again with Bahrain Visa this time.
