Washington-area schools are facing budget crises as a result of an influx of immigrant students, according to a recent report.

Since the 2005-06 school year, the percent of students enrolled in English proficiency classes has increased by an average of nearly 70 percent across seven school districts in the D.C. metro area, according to a report by the advocacy group, Federation for American Immigration Reform, which promotes tighter border security, an end to illegal immigration and reduced levels of legal immigration.
