Okay, I'm sure that your relatives are already here in us by this time. And I am glad I didn't read this before sending my brother to Colombia; I'm pretty sure I would have freaked out (AND, from a Venezuelan Standpoint .. a valid feeling).
After reading and reading and breaking down the USCIS statement, I asked my brother to get a vaccine approved by the WHO in Venezuela; one available is Sinopharm, a Chinese vaccine. Received 12/5/22 first dose. Traveled to USA 12/21. Second dose was supposed 12/25/22.
He traveled via BUS from Valencia to Cucuta - Entry and exit stamp in Colombian migration. Note: Venezuela migration does not stamp your exit passport if it is expired. And Cucuta-bog-Miami via AVIANCA. No issues. I hope this update helps someone!
