Emilio Gonzalez, director of United States Citizenship and Immigration Services (USCIS), announced his decision to resign from his current position, and will leave the office by April 18, reports the World Journal. Gonzalez has been criticized for new practices he had pushed, including the hike in application fees last July that resulted in a flood of applications before the cut-off date. Millions of applications are sitting in the backlog at USCIS, with more than a million applicants waiting for the U.S. citizenship in order to vote this year. USCIS’s “low efficiency” handling the backlog generated many lawsuits, and is one of the leading causes of Gonzalez’s resignation, according to the World Journal. Gonzalez recommended Jonathan Scharfen, deputy director of USCIS, to take his position.
