What is I-9 Form? I-9 form or Employment Eligibility Verification Form is a drafted file that has to be furnished by the employer, if he/she is hiring a new employee. This serves as a legal document mandated for the employees approval and to ascertain their entitlement to work legally in United States. An I-9 form must be completed for every person your firm hires to perform labor or services, in return for wages or remuneration (including food and lodging).Also, adhering to the mandatory requirement of Form 1-9, enables employers to easily conduct legal “right to work” form I-9 employment verification, on new employees. The I-9 form verification helps you to properly scrutinize the candidate’s status about his legal permission to work in United States. Any non-complying company, employing illegal immigrants or people who have not been entitled to work in U.S, may have to face sever legal and financial consequences as imposed by the Department of Homeland Security.
