Hispanic students did not show up for school in noticeable numbers Thursday and Friday in Alabama following a federal judge’s ruling Wednesday that upheld several provisions of a harsh state law restricting illegal immigration in the state.

The absence of Hispanic students has many education leaders worried that immigrant families are withdrawing their children from school to prevent state authorities from looking into their legal status.

The Pew Hispanic Center says the number of illegal immigrants in Alabama rose 380 percent between 2000-2010, from 25,000 to 120,000, and that illegals represent 2.5 percent of the total state population today.
