Premier combat troops have been ordered to the southern border, as part of Trump’s militarization of immigration.

Many remain determined to reach the U.S. through more dangerous means, riding freight trains, hiring smugglers and dodging authorities.

President Donald Trump’s plans to seal the U.S.-Mexico border and conduct mass deportations might soon run into a major roadblock: Mexico and the countries where the immigrants come from might not accept some of them back.

The Department of Defence said it would send 1,500 troops to the southern border to assist border-patrol agents and help build a wall separating America from Mexico. Some 2,500 National Guard soldiers and reservists are already there.
