In June 2011, House Judiciary Chairman Lamar Smith (R-Texas) and Ranking Member of the Senate Judiciary Committee Chuck Grassley (R-Iowa) both offered mandatory E-Verify bills in the United States Congress. Both bills would require all businesses to begin using E-Verify over a specified period of time. The bills would also reinstate the No-Match letter program along with other provisions that would help identify and fire illegal aliens who currently hold jobs.

Chairman Smith's bill (H.R. 2164) would phase-in E-Verify over a three-year period with 99% of the employers required to use the system within two years. The bill also increases fines and penalties for employers who knowingly hire illegal aliens.

Sen. Grassley's bill (S.1196) would phase-in E-Verify over a one-year period and would also require employers to run all current employees through the system.

Both of these bills are endorsed by NumbersUSA, and H.R. 2164 has the endorsement of the U.S. Chamber of Commerce and other major business groups.
