Migrant Influx at US-Mexico Border Amid Policy Changes.

Thousands of migrants are flowing north to the US-Mexico border ahead of policy changes, including the end of pandemic-related restrictions on people requesting asylum at the border on May 11. The prospect of new limits on asylum and uncertainty around what happens after the end of the restrictions has created an unnecessary sense of urgency for people making decisions with imperfect information. Migrant smugglers are taking advantage of this situation. The journey is punishing, with migrants hiking for several days over mountains in dense jungle contending with biting insects, venomous snakes, torrential rains, and mud-slicked mountain passes.
