Immigrants' social media records and log in information are now required to be included in the Department of Homeland Security's policy to conduct background checks, according to the Sept. 18 announcement.
The federal immigration department has been organizing "A-Files," which include social security numbers and government-issued benefits of immigrants, but it is now expanding the reach to social media accounts.
The policy is applicable to all immigrants who are waiting for their visas and green cards. It also includes naturalized U.S. citizens.
In addition, even U.S.-born citizens who converse with immigrants via social media could be subject to government investigations.
The government's decision to review social media accounts was motivated by the 2015 shooting in San Bernardino, Calif. Many terrorist attacks have also been discussed in advance on social media, prompting the Trump administration to make the decision.
The new policy will be effective starting Oct. 18.
