Driving Licence, CPR, Visa requirements

Dear Forum Members,

I would like to know the procedure and requirements of documents for obtaining a bahraini dirving licesnce for a pakistani national? is it a must to join a drving scholl, cos i have been drving in Pakistan for years now? how long does it take to obatin a drving licesence?

I would also like to know (or send me a link plz) the procedure for obtaining a CPR and how long does it take before one gets the CPR?

My employer is taking care of my visa issues. once i am in  baharain i would like to call my mother to bahrain on one month's visit visa. for that, what documents will i need? can i call her as a dependent , too? cos my employer is only sponsoring my wife's and children's visa.

Thanks
