New York: Nearly all applicants for a visa to enter the United States — an estimated 14.7 million people a year — will be asked to submit their social-media user names for the past five years, under proposed rules issued by the US State Department.

Last September, the Trump administration announced that applicants for immigrant visas would be asked for social-media data, a proposal that would affect about 710,000 people each year. The new proposal would vastly expand that requirement to cover some 14 million people each year who apply for non-immigrant visas.

Although officials did not specify which social-media platforms would be affected, the proposal is likely to cover the largest ones, like Facebook, Instagram, Snapchat and Twitter. It could also conceivably include social-media platforms based overseas, like QQ and Weibo in China and VK in Russia.

During his campaign, then presidential candidate Donald Trump promised "extreme vetting" of people seeking to enter the United States, and last March, the State Department directed consular officers around the world to step up scrutiny of visa applicants.

But the new proposal would add a tangible new requirement for millions of people who apply to visit the United States for work or pleasure, including citizens of such countries as Brazil, China, India and Mexico.
