Visa for India expats to go from Bahrain to Saudi!

Hi I am Archana, I am an Indian Hindu housewife , staying in Bahrain with my husband. My husband works in Saudi so he has got both Iqama and CPR Identity cards. I have only CPR card. But I would like to visit Saudi for few days. Please let me know the procedure for applying visa from Bahrain to Saudi for India non-Muslim expats.
Thank you
Archana

Muslim or non Muslim has nothing to do with it.

The visa has to be applied at the VFS Tahseel offices in Bahrain Financial harbour.  Go to their website and check all the requirements.   Your husband's company has to help by providing invitation letter.

If for tourist do you need invitation letter? I want to visit Al Khobar tq

The tourist visa is due to be rolled out at a later date.  It's not available right now.
