By the end of December 2024, approximately 936,500 individuals had entered the U.S. through CBP One appointments at the Mexico border, which was a key part of the Biden administration's strategy to create legal pathways for entry.

The specific number of people affected by this revocation of status is currently unknown, although DHS confirmed that some paroled individuals were notified.

The Biden administration has faced criticism for its use of parole authority, which has been utilized more than by any president since its inception in 1952, contributing to what some officials describe as the worst border crisis in U.S. history.

In addition to the app's new focus, the administration announced plans for a national registry requiring undocumented migrants to provide personal information to the government, raising concerns over enforcement and logistical challenges.

Tensions have escalated due to Donald Trump's recent decision to impose a 10 percent tariff on Australian exports, which was described as 'insulting' by some U.S. lawmakers.

US Trade Representative Jamieson Greer stated the tariff is part of efforts to address a $1.2 trillion trade deficit left by President Biden, suggesting the nation should 'run up the score on Australia.'

The Department of Homeland Security (DHS) has revoked legal status for migrants who entered the U.S. using the CBP One app, instructing them to leave 'immediately.'

The cancellation of paroles does not affect migrants in specific programs for Ukrainians and Afghans, according to DHS.

Additionally, the Trump administration announced an end to Temporary Protected Status (TPS) for 600,000 Venezuelans and approximately 500,000 Haitians, although a federal judge has temporarily halted this decision for some individuals.

The CBP One app, launched in 2020, allowed over 900,000 individuals to enter the U.S. since January 2023, granting them temporary legal status for two years under a presidential authority known as parole.

Affected migrants reportedly include individuals from Mexico, Honduras, and El Salvador, who have been advised of potential criminal prosecution and civil penalties for remaining in the U.S.

During a Senate finance committee hearing, Democratic Senator Mark Warner criticized the tariff, highlighting Australia's significance as a national security partner.
