The First Amendment indeed doesn’t apply to non-US individuals abroad, as much as I wish it were otherwise (and many other countries do take a more inclusive approach on such matters).
But the First Amendment does apply to the many US citizens and permanent residents who are being indirectly surveilled, profiled, and chilled in their speech as a result of the extra scrutiny of the foreign visa applicants with whom they interact and connect on social media.
