Please help on Queries (Riyadh)

I request for your personal help in giving me advice on following.
1. My budget for COMPOUND at SAR Protected content , for 3 Bhk. I find minimum rates at SAR Protected content western compounds. Are there any non western compounds near King Fahd street area. OR the only other option is apartment.

2. Do all employers keep custody of passports. Is this an IQUAMA requirement. Does this practice not make the expat at the mercy of employers?

3. Can I get 100% vegetarian tiffin delivered daily at home?

4. What are the school fees and admission charges in India centric (CBSE) International schools?
