to control or overthrow the government; or have, or will have, engaged in terrorist activities. The Attorney General or the Attorney General's deputy may maintain custody of such aliens until they are removed from the U.S. unless it is no longer deemed they should be removed, in which case they are released. The alien can be detained for up to 90 days but can be held up to six months after it is deemed that they are a national security threat. However, the alien must be charged with a crime or removal proceedings start no longer than seven days after the alien's detention, otherwise the alien will be released. However, such detentions must be reviewed every six months by the Attorney General, who can then decide to revoke it, unless prevented from doing so by law. Every six months the alien may apply, in writing, for the certification to be reconsidered. Judicial review of any action or decision relating to this section, including judicial review of the merits of a certification, can be held under habeas corpus proceedings. Such proceedings can be initiated by an application filed with the United States Supreme Court, by any justice of the Supreme Court, by any circuit judge of the United States Court of Appeals for the District of Columbia Circuit, or by any district court otherwise having jurisdiction to entertain the application. The final order is subject to appeal to the United States Court of Appeals for the District of Columbia Circuit. Provisions were also made for a report to be required every six months of such decisions from the U.S. Attorney General to the Committee on the Judiciary of the House of Representatives and the Committee on the Judiciary of the Senate.

Congress wanted the primary focus of development of the entry-exit data system was to be on the utilization of biometric technology and the development of tamper-resistant documents
