 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").
