1. Border Patrol agents have doubled and the 2013 Senate bill proposed a bigger increase than Trump Trump's proposal would represent a 24 percent increase in authorized jobs. The bipartisan immigration bill passed by the Senate in 2013 would have gone even further, expanding the Border Patrol to more than 38,000. Federal spending on the Border Patrol has also grown rapidly, climbing from $1.4 billion in fiscal year 2002 to $3.8 billion last year. 2. Apprehensions are down Apprehensions have fallen 79 percent from their peak in 2000. This is generally seen as a sign that fewer people are trying to cross the border illegally. 3. Spending on enforcement is way up As with the Border Patrol, federal spending on Immigration and Customs Enforcement, which shares responsibility for enforcing immigration law, has already jumped by 84 percent since 2005.

In the meantime, he wants to prioritize deportation of "criminals, gang members, security threats, visa overstays" and those who rely on public welfare, along with "millions of recent illegal arrivals." The Washington Post estimates that, in all, some 6 million people could be subject to deportation if Trump's promised policies were to take effect. 5. Criminal deportation because of foot-dragging or something else? Trump suggested the only reason criminals haven't been deported already is federal foot-dragging. In fact, local and state governments sometimes refuse to cooperate with federal immigration officials, for fear that overzealous deportation practices would target low-level offenders and alienate local immigrant communities. 6. Go back to ... Canada? Trump says he'll make a priority of removing visitors who overstay their visas — an estimated half-million people each year.
