The other thing which you can also mention in your contract is that you are allowed to change your sponsors in the future.

This means that when you want to move to another company say within qatar, the company you are starting with now would be able to provide a NOC (no objection certificate/letter), otherwise the go is that when a qatari contract terminates/expires and is not renewed the employee must go back to their country.

But with a NOC when you terminate a contract or it expires the company issues a letter mentioning that they have no objection to allowing you to change your sponsor/employer.

It just makes it that much easier...but this is all dependant on which company you deal with...and its not obligatory for them to do this...but generally everyone is nice.
