From KERA:
A growing number of Mexicans are fleeing their homes and heading to the U.S. border to seek asylum, driven by a surge in violence. But once they get to a port of entry, many of them are blocked.
A policy called metering limits the number of asylum seekers allowed into the U.S. each day. That leaves some Mexicans stuck in their own country, terrified the violence they’re fleeing may catch up with them.
