Roxham Road Meets a Dead End? U.S.-Canada Safe Third Country Agreement Is Revised

The revised U.S.-Canada Safe Third Country Agreement closes what critics call a loophole that incentivizes unauthorized border crossings of asylum seekers. While responding to Canadian concerns of increasing irregular arrivals from the United States, the change—taken in tandem with U.S. moves at the U.S.-Mexico border—suggests that the Biden administration increasingly wants to rely on neighboring countries to respond to rising asylum claims.

This article evaluates Biden's early actions and what they suggest about the White House's ambitions on immigration.

Nearly 3 Million U.S. Citizens and Legal Immigrants Initially Excluded under the CARES Act Are Covered under the December 2020 COVID-19 Stimulus

The pandemic-recovery stimulus package that passed Congress in December rectified what many had viewed as a significant oversight in the earlier CARES Act: Its exclusion of U.S. citizens and legal immigrants in mixed-status families. MPI researchers estimate nearly 3 million U.S. citizens and legal immigrants excluded from the earlier legislation can receive the later relief, as well as qualify retroactively for the CARES Act payment, as this commentary explores.
