The US State Department announced Wednesday it would begin reviewing online social media accounts for all student and exchange visitor applicants as part of its visa screening process.

All students and exchange visitors applying for visas under the F, M, and J non-immigrant classifications will be required to make their social media profiles public under the new guidance as part of the new US vetting process. The release read:

The State Department is committed to protecting our nation and our citizens by upholding the highest standards of national security and public safety through our visa process. A U.S. visa is a privilege, not a right. We use all available information in our visa screening and vetting to identify visa applicants who are inadmissible to the United States, including those who pose a threat to U.S. national security.

The new policy comes in the wake of President Donald Trump’s administration’s efforts to limit or terminate international student visas and records.

The executive director of the Knight First Amendment Institute at Columbia University, Jameel Jaffer, said in a statement that the new social media requirements for visa applicants will chill political speech:

This policy makes a censor of every consular officer, and it will inevitably chill legitimate political speech both inside and outside the United States. During the Cold War, ideological vetting by consular officers resulted in the exclusion from the United States of some of the 20th century’s most significant artistic and intellectual figures, including Pablo Neruda, Doris Lessing, Gabriel Garcia Marquez, and Graham Greene. This new State Department policy is a digital-age version of a policy that history has already discredited.

The J Visa is for exchange visitors seeking to participate in work-and-study-based programs in the US. The F Visa is for individuals attending a school or academic program full-time. The M Visa is for those participating in a non-academic or vocational study program for one year, with the option to apply for extensions up to three years.

Scheduling nonimmigrant visa applications for the F, M, and J visas will resume “soon” after reviews were paused on May 27 pending the newly released guidance.
