Incoming president Donald Trump has vowed to end the CBP One app, which people outside the U.S. use to book appointments to petition for asylum.

U.S. District Judge Jon Tigar blocked a similar policy during the Trump administration, and immigrant advocates had urged him to do the same in this case.

Biden administration rules have one main legal pathway to seek asylum for migrants already at the border: a mobile app called CBP One. Immigrant advocates and immigration hardliners have objections.

Immigration authorities touted a major update meant to improve CBP One, an app that's now the main authorized portal to seek asylum at the border. But migrants in Juárez say it's still not working.
