When did the United States start collecting social media information about immigrants?

According to US media reports, the US Department of Homeland Security intends to collect social media information of all immigrants, including permanent residents and naturalized immigrants.

On September 18, the Federal Gazette published a new regulation, requiring that items such as "social media names, relevant identity information and search results" be added to immigration files. This regulation will be implemented on 10+08.

According to the document, the government hopes to expand the categories of recorded content and collect information including social media names, relevant identity information and search results. In addition, the information source catalogue will be updated to include public information obtained from the network and information obtained according to the information sharing agreement.

In May of this year, the Trump administration introduced new US visa regulations, requiring visa applicants to provide their social media information of the past five years and their resumes of 15 years. A few months ago, the White House began checking visa applicants' Twitter and Facebook accounts.
