an employer could not refuse to hire a candidate because his I-9 revealed that he was a non-citizen (such as a permanent resident or a refugee) rather than a U.S. citizen. For this reason some immigration lawyers advise companies to avoid requiring an I-9 until a candidate is hired rather than risk a lawsuit. As another example, a company could not insist that an employee provide a passport rather than, say, a driver's license and social security card. Another anti-discrimination provision requires that employers must enforce I-9 compliance in a uniform manner. For example, an employer must not require some employees to complete an I-9 before being hired, but allow others to complete the form after starting employment. Employers must not assume that the employee is unauthorized to work just because the individual either could not bring the proof of employment authorization or has brought the unaccepted documents until the start date of the employment. Instead, employers should encourage that employee to bring the acceptable documents which are under the List A, B and C. Employers may terminate the employment only if the employee cannot attest the person's work authorization by bringing the proof after the start date. The Office of Special Counsel for Immigration-Related Unfair Employment Practices ("OSC") is a section within the Department of Justice's Civil Rights Division that enforces the anti-discrimination provision of the Immigration and Nationality Act ("INA"). The OSC can help workers by calling employers and explaining proper verification practices and, when necessary, by providing victims of discrimination with charge forms. Upon receipt of a charge of discrimination, OSC investigations typically take no longer than seven months. Victims may obtain various types of relief including job relief and back pay. OSC also has an extensive outreach program. It provides staff to speak at outreach events throughout the country, and has free informational brochures, posters and tapes for distribution. Types of discrimination The OSC investigates the following types of discriminatory conduct under the anti-discrimination provision of the Immigration and Nationality Act (INA), 8 U.S.C. § 1324b: Citizenship or immigration status discrimination With respect to hiring, firing, recruitment or referral for a fee by employers with four or more employees, employers may not treat individuals differently because they are or are not U.S. citizens or work-authorized individuals. U.S. citizens, recent permanent residents, temporary residents, asylees and refugees are protected from citizenship status discrimination. However, permanent residents who
