The Department of Homeland Security has postponed proposing an end to the H-4 work visa, which lets the spouses of H-1B workers with pending green cards find employment in the United States, according to a court filing. They now plan to issue the proposal in June — instead of their original goal of February — after USCIS "reevaluated the rule and determined that significant revisions to the draft proposal were necessary."

Why it matters: The Trump administration and DHS faced several setbacks in their attempts to crack down on immigration policies in February — from DACA, to the travel ban, to defunding sanctuary cities. Now, the spouses of these H-1B holders will face at least a few additional months in legal limbo before USCIS offers clarity regarding their work authorization.

Editor’s note: This article has been updated to more accurately reflect that this potential policy change would only affect the spouses of H-1B holders with pending green cards.

Moderna announced that it plans to file with the FDA Monday for an emergency use authorization for its coronavirus vaccine, which the company said has an efficacy rate of 94.1%.

Why it matters: Moderna will become the second company to file for a vaccine EUA after Pfizer did the same earlier this month, potentially paving the way for the U.S. to have two COVID-19 vaccines in distribution by the end of the year. The company said its vaccine has a 100% efficacy rate against severe COVID cases.

Right now, everyone from Senate leaders to the makers of Netflix's popular "Social Dilemma" is promoting the idea that Facebook is addictive.

Yes, but: Human beings have raised fears about the addictive nature of every new media technology since the 18th century brought us the novel, yet the species has always seemed to recover its balance once the initial infatuation wears off.

Young people's next big COVID test

Young, healthy people will be at the back of the line for coronavirus vaccines, and they'll have to maintain their sense of urgency as they wait their turn — otherwise, vaccinations won't be as effective in bringing the pandemic to a close.

The big picture: "It’s great young people are anticipating the vaccine," said Jewel Mullen, associate dean for health equity at the University of Texas. But the prospect of that enthusiasm waning is "a cause for concern," she said.
