A bill to amend the Immigration and Nationality Act and the Social Security Act to require that specific alien and citizenship information be provided prior to the issuance of a social security card, to require that social security cards which cannot be duplicated be issued, to require that these cards be presented to employers by prospective employees before obtaining employment, to provide penalties against employers for violating the provisions of the Act and for other purposes.

Amends title II (Old-Age, Survivors and Disability Insurance) of the Social Security Act to require that any social security account number assigned, after this Act becomes effective, be on a card or in such other form as will easily reveal any illegal alteration or duplication.

Requires, in the case of cards issued to aliens who are not in the United States under conditions which make it lawful for them to engage in employment, that such card be marked to indicate that such individual may not be legally employed. Authorizes the reissuance of such card without such mark at such time as it is determined that the alien may lawfully engage in employment in the United States.

Establishes criminal penalties for individuals who knowingly employ alien holders of cards which indicate that they may not lawfully engage in employment in the United States.
