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