With respect to the current 60 day covid extension which is set to be discontinued at the end of September (if reports are accurate).
Say if you have a non-immigrant O 90 day entry (visiting family) expiring mid October. If we went into extend for 60 days before the discontinuation (ie before the 27th of September) - will the 60 days be from the end of September or will it be from mid October?
TLDR : Answer Summary
The 60-day COVID extension must be applied for before it is discontinued at the end of September. If you apply for the extension before the 27th of September, it generally begins on the date of application and lasts for 60 days, regardless of your original visa's expiration date.
