Extradition shall also be granted for illicit association, as provided by the laws of Costa Rica , to commit any offense described in paragraph (1) of this Article, and for conspiring as provided by the laws of the United States of America , to commit any such offense. (3) For the purpose of this Article, an offense shall be an extraditable offense: (a) Whether or not the laws of the Contracting Parties place the offense within the same category of offenses or denominate the offense by the same terminology; or (b) Whether or not the offense is one for which United States federal law requires, for the purpose of establishing jurisdiction in a United States federal court, proof of interstate transportation, or use of, or effect on, the mails or other facilities affecting interstate or foreign commerce.
