Legally it is, but given that it's one of the most non-violent offenses one could commit, and given that there are still ways of receiving identifying info that can be used to at least track employment (undocumented immigrants can still be issued tax IDs, but can neither pay into or receive social security benefits with it), I'd say that it's the law and system that's unjust, rather than necessarily a problem with the people coming throughWell, I think that's kinda funny. Isn't being an undocumented immigrant a crime?
