CATO posted an analysis on the early phase of President Trump's immigration crackdown:

Refugee admissions are down by 90%, asylum entry is down 99%, permanent legal immigrants are down 50% or more, H-1B in total is cut at least 25% and 80% to 90% for new applicants. Foreign students down went down 40%, spouses and fiancé/es down 65. President Trump not only has a net outflow of illegals but an increasingly narrow entry for legal migrants 'temporary' and permanent.
