GAO on E-Verify
In its report of June 2008, the U.S. Government Accountability Office (GAO) stated that while E-Verify may help employers detect fraudulent documents (and I would say indirectly), it cannot fully address the use of legitimate documents. This issue can only be fully addressed by individuals owning those documents. The GAO also points out that E-Verify is vulnerable to employer misuse and even, fraud.
Given our adversarial system many employers worry that firing an 
employee based on what could turn out to be an E-verify error could still land them a discrimination charge under the Immigration Reform and Control Act of 1986 (IRCA). IRCA prohibits discrimination when hiring and firing based on the basis of citizenship status or national origin. Such discrimination could result from firing an individual based on lack of employment authorization when the individual is in reality authorized.
