Trump's USCIS and State Department have rolled out a series of rule changes to restrict legal immigrants, current and new.

This includes removing protections for family members, ending the 'dropbox'/remote renewal process and mandating in-person interviews for H-1B, and a time limit for student visas. Not to mention the suspension of refugee and asylee entry. Next is ending OPT, and a formal end to birthright citizenship, when SCOTUS rules.
