After Bombing, New Scrutiny For Holes in Immigration Net
When Mohammed A. Salameh, one of the two main suspects in the bombing of the World Trade Center, entered the United States as a temporary foreign visitor in 1987, he quickly slipped through a Federal immigration bureaucracy that had no plan or hope of ever tracking him amid the nation's vast tide of illegal aliens. He joined about 500,000 other visitors who drift from sight annually as their visas lapse. They usually are never traced or thought of again until such a moment as now when startled, angry Americans begin questioning whether the United States immigration system presents a model of sanctuary or of porousness for the global throngs seeking entry.
