As I understand it, the younger brother Dzhokar was a naturalized citizen, but the big brother Tamerlan was not. I'm reading all this stuff now that Tamerlan was on welfare. So is that how it works, you can be on welfare and you don't even have to be a full on citizen? Why would we even let them live here then? Talk about move to a country and then be a burden on it without even having full citizenship.
