Indian National, Can Multiple visit visa holder of Saudi Arabia with husband, having valid resident visa of UAE & OMAN travel Bahrain by road ? to UAE as well?

If you are a GCC resident and have a KSA visa which doesn't state "AIR" in mode of travel; you can travel to Bahrain.

For UAE, if you don't have resident visa of UAE, you must apply for a visa before.  Despite your other GCC residency.
