Urgent. travelling from jeddah to bahrain

I am planning to go to bahrain. I have multiple visit visa at saudi. I will go to Manama by air from Jeddah and I plan to re-enter KSA through causeway to Dammam.

Will there be a problem at the immigration? I heard some say, there is.

Please help...

I can't foresee you having any problems

I also don't think there will be any problem in arriving by air and leaving by road.
