President Trump signed a little-noticed executive order last week that rescinded an Obama-era goal to speed up visa processing.

The brief directive strikes part of a 2012 order signed by former President Obama that instructed the State Department to “ensure that 80 percent of nonimmigrant visa applicants are interviewed within three weeks of receipt of application.”

White House officials frame the decision as an effort to strengthen security. While the change could significantly extend wait times for people seeking to travel to the U.S., they say it doesn’t make sense to rush a visa process that could prevent a terrorist from entering the country.
