Permanently reauthorizes E-Verify (removing the September 30, 2015 termination date) and requires employers to verify all existing employees not previously checked through E-Verify within 1 year

Significantly increases civil penalties for hiring violations: first offense $2,500-$5,000 (up from $250-$2,000), second offense $5,000-$10,000, third offense $10,000-$25,000; criminal penalties up to $30,000 per unauthorized worker and 1-10 years imprisonment for pattern violations

Establishes an Employer Compliance Inspection Center within ICE to centralize worksite enforcement audits and creates mandatory information-sharing between Social Security Administration, IRS, DHS, and Treasury to identify unauthorized workers

Preempts state and local laws that prohibit E-Verify use, provides employer liability protection for good-faith reliance on E-Verify results, and requires employers who receive final nonconfirmation to immediately terminate the employee and report information to DHS
