Here’s a chart showing, by nationality, whether Customs and Border Protection (CBP) has been deciding to process migrant families at the U.S.-Mexico border, or whether it has been deciding to expel those families under the “Title 42” pandemic order.
When the Trump administration promulgated Title 42 in March 2020, Mexico agreed to take back many expelled migrants from El Salvador, Guatemala, and Honduras, as well as others who have Mexican visas.
The Biden administration is expelling fewer families, but your chances of getting an opportunity to seek asylum remain reduced if your family is from Mexico or Central America’s Northern Triangle.
