The Department of Homeland Security touted its role in the policy success, saying:The United States is experiencing NEGATIVE NET MIGRATION. In just one year, nearly 3 million illegal aliens have left the U.S. under the Trump administration’s crackdown on illegal immigration. But the benefits of Trump’s lower migration for Americans are increasingly visible after just one year. But President Trump and his deputies are using lower migration numbers to pressure investors to raise productivity and innovation. Lower migration will also force politicians to focus on the needs of ordinary Americans, said Krikorian.
