Trump hasn’t needed the wall to remake U.S. immigration policy

3. Immigration law enforcement is much more aggressive within the U.S. Much of the national immigration discussion is focused on the U.S.-Mexico border. But Immigration and Customs Enforcement, the federal agency that enforces immigration laws away from the border, is where some of the biggest changes are happening. In the fiscal year that covered much of Trump’s first year in office, ICE made about 143,000 arrests, compared with 110,000 during the last complete fiscal year of Obama’s presidency.

4. People from countries included in Trump’s travel ban basically can’t come here. Comparing fiscal year 2016 with January through May of 2018, the U.S. has issued far fewer visas in an average month to people from Iran, Syria and Yemen — at least an 80 percent drop for each country. There has been an even larger drop in the number of visas granted to people from Iran and Yemen who want to move to the U.S. permanently.
