Trump has pledged to reduce immigration. But by narrowing the already limited legal pathways into the U.S., migrants will just recalibrate their plans and resort in greater numbers to hiring smugglers, experts say. In many cases that will mean turning to organized crime groups that increasingly profit from migrant smuggling.

Donald Trump's win in the United States presidential election instantly changed calculations for millions of migrants or potential migrants across the globe.

Trump won a second term Tuesday with promises to enact an unprecedented crackdown on immigrants. Advocates are taking him at his word and taking steps to protect vulnerable migrants.
