that is NOT correct :( The O/P holds a year-long, multiple re-entry Non-Immigrant Type O-A (Long Stay) visa. That visa allows unlimited entry for the validity (a year from the date it was issued or in the O/P's case from Nov 6, 2020 to Nov 5, 2021) and every entry will get them stamped in for a year from the date they enter (OR as long as their health insurance is good for, up to one year)
