I was the sponsor of my brother in law in his migration process, he doesn't have social security yet. Can I add him as a dependent? we have been paying everything for him

In order to claim someone as a dependent, they must have a SSN or an ITIN.  

First and foremost, a dependent is someone you support: You must have provided at least half of the person's total support for the year — food, shelter, clothing, etc. If your adult daughter, for example, lived with you but provided at least half of her own support, you probably can't claim her as a dependent.
