Individuals with a precarious social media history have been put on high alert following Donald Trump's latest directives on U.S.

visa and Green Card applications.

Under the directive, applicants for Green Cards will be required to disclose their social media history as part of a strict vetting process.

The policy, which has been in effect since 2009, requires visa and Green Card applicants to provide usernames for all social media platforms used in the past five years, along with previous email addresses and phone numbers.
