From bh to sa

I don't know if there was a query about this before. I am working here in saudi and my wife works in bahrain. I crossed the boarder almost every two weeks to be with her. I am planning to apply a visit visa for her so that she could be able to come here on saudi holidays. May I know the requirements and procedures for her to undergo and process in bahrain? She works as a beautician in a salon.

Tnx,

Visit Istikdaam office and mofa (ministry of foreign affairs) for exact requirement. Btw visit visa can last 6 months and it will be single entry.
