Biden at the Two-Year Mark: Significant Immigration Actions Eclipsed by Record Border Numbers

At his term's midpoint, President Joe Biden has relied on executive action to advance his immigration agenda more than his predecessors, including Donald Trump.

Amid Record Venezuelan Arrivals, Biden Administration Embraces Border Expulsions Policy

The Biden administration’s policy to expel some Venezuelan border arrivals to Mexico marks a significant reversal. For the first time, the U.S. government is invoking the controversial Title 42 expulsions policy not on public-health grounds but as an explicit immigration enforcement measure. The expulsions are being paired with a new humanitarian parole program for up to 24,000 Venezuelans. This article assesses the policy and the uneven treatment of humanitarian migrants by nationality.

As EU Member States struggle to deliver on the European Union's call to expand channels for foreign workers, they should focus more on attracting the middle- and low-skilled third-country nationals needed by the labor market yet for whom few opportunities for admission exist. They also would do well to consider their migration policies in light of labor market, foreign policy, and development objectives, rather than as a means to reduce irregular migration, this report cautions.

Supreme Court Asylum Ruling Latest Sign Judiciary Is Not the Brake on the Trump Administration that Immigration-Rights Activists Sought
