Twenty-one people who allegedly helped more than 1,000 foreign nationals fraudulently obtain student visas were arrested this morning by federal agents in a nationwide sweep.

A U.S. Immigration and Customs Enforcement attorney was charged on Wednesday. Authorities say he forged a document to make it look like a Mexican citizen who wanted to stay in the United State was not eligible to do so.

U.S. authorities in Pakistan could have sought - but did not - a full background security investigation of San Bernardino shooter Tashfeen Malik before granting her a visa to enter the United States in 2014, according to a U.S. official familiar with the matter.
