It’s confusing. I had a valid visa until Oct 2020, but was the kind you get overseas that requires exit and re-entry every 90 days. Due to COVID that was impossible, so I think it was a COVID extension, not one to visit family.
My last entry was valid until 9 May 2020. It looks like I did an extension in July that gave me until 14 September 2021 but that was just to avoid having to exit and renter. My original visa was still valid.
