The new restrictions, which Trump is expected to sign Monday afternoon, will prevent foreign workers from filling 525,000 jobs, according to White House estimates. Trump on April 22 ordered a 60-day freeze on several categories of family and employment-based immigration visas, limits that have now been extended through the end of 2020. While U.S. citizens can continue to sponsor spouses and minor children, Trumps orders will bar most other categories of applicants, affecting more than half of the approximately 460,000 immigration visas issued last year. Trump administration officials have defended the restrictions as a sensible measure to protect U.S. workers amid unemployment levels that are the highest since the Great Depression. This is a victory for the immigration hawks within the White House, Krikorian said.
