In an effort to deal with the situation after the September 11 event, the U.S. Congress on October 26th 2001 passed the "Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001." a.k.a. USA PATRIOT ACT. According to the United States Department of Treasury (2001), the Act aims to deter and punish terrorist acts in the U.S. and around the world, to strengthen law enforcement investigatory tools, and other purposes. Several aspects of the Act were related to immigration policy, detention and deportation. USA PATRIOT ACT encourages immigration law enforcement and border security. The Act allows authorized agencies to search, monitor, detain, or even deport terrorist suspect. It also allows the agencies to keep foreigners up to 7 days for interrogation. On the other hand, the Act helps the federal government strengthen border security, especially along the northern border with Canada [Ton]. USA PATRIOT has set a step for most of changes in immigration policies in a decade after the September 11 event. Federal government and the public saw the immigration policy enforcement as an important part of national security.
