US citizens who apply for a job will need prior approval from Department of Homeland Security under the terms immigration bill passed by the Senate this week.

American Civil Liberties Union pointed out that the DHS's Employment Eligibility Verification System (EEVS) is error plagued and if the department makes a mistake in determining work eligibility, there will be virtually no way to challenge the error or recover lost wages due to the bill’s prohibitions on judicial review.

Even current employees will need to obtain eligibility approval from the DHS Within 60 days of the Immigration Reform Act of 2006 becoming law.

"EEVS would be a financial and bureaucratic nightmare for both businesses and workers," said Timothy Sparapani, ACLU Legislative Counsel. "Under this already flawed program no one would be able to work in the U.S. without DHS approval - creating a ‘No Work List’ similar to the government’s ‘No Fly List.’ We need immigration reform, but not at this cost."

The act allocates US$400 million for the implementation of the EEVS, but the Congressional Budgeting Office estimates the system to cost in excess of a billion dollars.
