Under the Immigration Reform and Control Act of 1986, as amended by the Immigration and Nationality Act, all United States (U.S.) employers are required to obtain and retain information concerning each employee's eligibility to work in the U.S. The information to be collected generally consists of the employee's social security number, address, date of birth, and other personally identifiable information sufficient to make an eligibility determination. At the time of employment, the information is to be recorded on Form I-9, Employment Eligibility Verification. Federal law requires that these forms be retained for three years after the date of hire or one year after the employment is terminated, whichever is later. Failure to comply with Federal Law requirements associated with 1-9 forms may result in civil penalties against the employer.
