The new travel screening is for those deemed a national security threat.

Visa applicants who the US State Department suspects may pose a danger if allowed into the country will be required to provide their social media handles on a new application (PDF) the government just unveiled.

The new vetting, the State Department said, would likely ensnare about 0.5 percent of visa applicants annually—the equivalent of roughly 65,000 people. The screening would apply to visa applicants "who have been determined to warrant additional scrutiny in connection with terrorism or other national security-related visa ineligibilities," according to a notice in the Federal Register by the State Department.

In all, applicants that the government deems suspicious would be required to disclose (PDF) their previous passport numbers, five years of social media handles, telephone numbers, and e-mail addresses. The plan also calls for US-bound travelers to supply 15 years of biographical data.

The Office of Management and Budget approved the new procedure on May 23 as part of President Donald Trump's plan to enhance the vetting process for visa applicants. It was included as part of a Trump immigration executive order that contained a temporary ban on people from several Muslim-majority nations.

Trump's travel order has been halted by a federal appeals court. The Trump administration asked the US Supreme Court on Thursday to reverse that decision. The appeals court, however, did not disturb Trump's call for harsher visa vetting procedures.
