Contract term/clause about Visa

Dear friends,

I from India and I have received good job offer in Muscat and planning to relocate me and my family (wife and two kids) there soon. In the contract it is mentioned that "you will be provided Oman visa and family visa (for spouse & kids)"

I want to know whether this statement is good enough to confirm that me & my family members will be receiving Oman resident cards? I'm curiously asking because I want to make sure kids can join schools when resident cards are issued to us as it will be mandatory right.

when I asked employer they are saying not to worry and they mention like this in the offer for everyone. Kindly advise me on this regards whether to ask them to mention "Resident cards" in the offer or this is ok?
