Amends the Immigration and Nationality Act to prohibit the U.S. admission of aliens supporting international child abductors and relatives of such abductors until the child is surrendered to the legal custodian and such child and custodian are permitted to return to the United States or the custodian's residence. (Currently such prohibition applies to relatives of abductors.) Expands the scope of "relatives" to include cousins, uncles, aunts, nephews, nieces, and grandparents. Includes the spouse of the abducted child within such prohibition.

Directs the Secretary of State to: (1) identify inadmissible aliens supporting child abductors and relatives of abductors; and (2) provide notice, upon request, to custodial parents and guardians if such an alien has been authorized to enter the United States.
