A bill to halt the introduction of U.S. Combat Units into Central America without the approval of Congress.

Prohibits sending combat troops into Costa Rica, El Salvador, Guatemala, Honduras, or Nicaragua for training exercises or any other purposes unless: (1) Congress has authorized their presence in advance by a joint resolution signed by the President; or (2) the presence of such troops is necessary to provide for the immediate evacuation of U.S. citizens, or to respond to a clear and present danger of military attack on the United States. Declares that, in either case, the President should advise and, to the extent possible, consult in advance with the Congress.
