New Biden administration guidelines encourage immigration prosecutors to support dismissing many low-priority deportation cases and focus on criminals, threats to national security, and other priorities. This move could have a major impact on clearing backlogs in the overstretched U.S. immigration court system, resulting in quicker determinations in removal and asylum cases, where wait times can presently stretch for years.

Requirements that international travelers and migrants prove vaccination against certain diseases are about as old as vaccines themselves. In some cases, vaccine certificates predated the existence of government-issued passports.

The nearly 11 million Mexican immigrants in the United States represent almost one-quarter of the country’s entire immigrant population, and as such are the largest foreign-born group. But their numbers have been declining, shrinking by 7 percent between 2010 and 2019. Among recently arrived immigrants, those from China and India now outpace Mexicans for the first time.

Before entering office, President Donald Trump promised to deport millions of unauthorized immigrants. Yet despite his general successes in creating a more restrictive and punitive immigration system, this goal has eluded his administration. So-called “sanctuary” policies implemented by state and local governments to limit their cooperation with U.S. Immigration and Customs Enforcement have been a key reason why arrests and removals have not reached earlier peaks.
