Even immigrants who have not been paid "on the books" would likely use their work history as proof of their residency in the United States before the December 31, 2011 cutoff date, thereby giving the government proof of the amount in taxes they would owe. As Louis DeSipio, a professor of political science and Chicano/Latino studies at the University of California, Irvine, explained, workers who provide work history could "help government officials determine whether appropriate [taxes] have been paid": "If it's obvious in those employment records that they have not been paying taxes, I think in that case they [The IRS] would make some effort to collect those funds," DeSipio said.
