José Martinez applies for a job with American Heartland Corporation. Sparky Foster, personnel director, asks José if he is a U.S. citizen. José replies in the negative but then produces a green card signifying his status as a resident alien with working privileges. Sparky silences José and then tells José, “At American Heartland, we hire only U.S. citizens.” José is considering suing under Title VII. How would you advise him?
