The Trump Administration announced it would deny entry to foreign nationals who had traveled to China in the last 14 Days. The ban, which Trump continues to call a “very strong ban” does not include anyone but non-US Citizens or residents or their families coming from China. If you are a permanent US resident or even just a family member of a permanent resident, even if you have been in Wuhan for the last month, you are free to return to the US. The same people would have been sent through an entirely separate Airport terminal in Korea, immediately screened for symptoms, tested for the virus and required to self quarantine for a minimum of 2 weeks. Here, no checks are made on your health, no restrictions placed on your movement. The “very strong ban” only blocks foreigners from entering the country.
