President Bushs plan to let many illegal aliens stay in the U.S. as guest workers has lured a wave of immigrants across the Southwest border, the Los Angeles Times reported this week. The proposal has stalled in Congress and is unlikely to be approved this year. Many Mexicans are reportedly under the mistaken impression that a mass amnesty has already been enacted, and they have come looking to apply. The number of illegal immigrants caught at the border has risen 30 percent in the last seven months. In reports to their superiors, Border Patrol agents said the influx had grown so heavy that they worried terrorists might be able to sneak in unnoticed among the arriving crowds.
