Migrants in Mexico who were hoping to come to the U.S. are adjusting to a new and uncertain reality after President Donald Trump began cracking down on border security.

The U.S. southern border has seen a sharp drop in migrant encounters entering between ports of entry at the southern border, according to a CBP source.

The US-Mexico border is effectively closed off to migrants seeking asylum in the United States within hours of President Donald Trump taking office, an extraordinary departure from previous protocols that has left many concerned migrants in limbo.
