If you've never been to Metamoros, Mexico, just across the border from Brownsville, Texas,

Felicia, Ranjal, Samponaro wants you to know what the city's park looks like, because

it's not a park anymore.

It's a makeshift home for people trying to get to the U.S.

Whole families live out in what used to be Metamoros' park, and at its height, like

a month or two ago, we had over 2,000 people living in this park, and this small space one

on top of the other.

So there's also trash, there's only four porta-potties for all of these people.

So it's just really unsanitary, and then you're living outside amongst the cartels that

run those cities.

Cities like Metamoros and Renosa, which also has a large encampment.

The camps have grown in shrunk over the years, largely depending on U.S. immigration policy.

The people living in them often come from places like Venezuela or Honduras.

Some have endured terrifying journeys just to get to Mexico.

They don't have tents, so what they've done is they have repurposed trash bags and blankets,

and they've gotten like sticks or branches, and they've dug the branches into the ground

like you would a tent.

Felicia runs the sidewalk school, which provides education, medical care, and other assistance

to families seeking asylum in the U.S.

And since January, that has also meant providing tech support.

Because if you want to apply for asylum, you have to do it through an app.

An app called CBP1 from Customs and Border Protection.
