A recent story by Associated Press reports that Immigration and Customs Enforcement (ICE) has begun a crackdown in all states, checking employers large and small to verify that employees are legally authorized to work. Romben Law, APC in Los Angeles represents companies as well as individuals.
Most employers and even some individuals are required to maintain Form I-9 Employment Eligibility Verification on all regular employees. If a company does not maintain its I-9s properly, the company can be fined. If a company is in doubt about whether its I-9s are properly completed and maintained, the company should contact reliable immigration law counsel to arrange for a review of the files. –jcf
