Can I claim my brother-in-law as a dependent if he lived with us for half of 2016? He was studying here as an international student and no longer resides in the US.

My brother-in-law was staying with us for about 6 months in 2016 as a student. He wasn't allowed to work so he didn't pay any taxes but he did have a SSN. He left the US around July and will not be filing for his own taxes. Can I claim him as my dependent?
