"If you came on student visa i don't think you worked on campus to pay your tuition fees neither did anyone you know." - can't compare working under the table to pay tuition, ( i.e. make in US and spend in US ) to coming to US uninvited, bring drugs, crime and the failed culture with you, bypass all the legal applicants waiting for years, cheat the system every way possible and live off of welfare that came from tax paid by hard working Americans.

In fact this is exactly why immigration reform is needed to make it merit based. An America loving, highly skilled international student should get priority not the lotto winners or fake asylees or the anchor baby scammers. But of course Dems don't like accomplished immigrants, they are hard to be brainwashed and can't be scared with potential loss of welfare.
