The U.S. Citizenship and Immigration Services (USCIS) is preparing to furlough nearly 70 percent of its workforce as the agency faces budget shortfalls amid the coronavirus pandemic, a spokesperson for the agency said Wednesday.

About 13,400 of the agency’s 20,000 employees will receive notice that they will be furloughed starting Aug. 3 if the agency does not receive additional funding from Congress, the spokesperson said in a statement.
