“The primary driver of this crisis is that President Donald Trump’s policies are sending thousands of migrants back to Mexico, where there isn’t enough safe, temporary housing in which they can stay.
In 2018, US Customs and Border Protection officials started limiting the number of asylum seekers it processes at ports of entry each day. Those waiting had to do so in Mexico, where migrant shelters are at capacity. Many have been forced to sleep on the streets. The amount of names on lists of those waiting to be processed exceeded 26,000 in August.
Once they are processed, though, they may quickly be returned to Mexico under the Trump administration’s “Remain in Mexico” policy, officially known as the Migrant Protection Protocols (MPP). More than 56,000 migrants have been sent back to await decisions on their US asylum applications.”
