INS to be Restructured: WASHINGTON –– The Bush administration announced Wednesday a major restructuring of the Immigration and Naturalization Service to separate law enforcement and service duties. The change fulfills a campaign pledge by President Bush to try to reduce the long waits endured by people who apply for benefits such as naturalization or permanent residency. It also seeks to address deficiencies in how the INS tracks foreigners who enter the country. Thirteen of the 19 hijackers in the Sept. 11 terrorist attacks entered the United States legally, but no entry records exist for the other six.
