Will renewing my Non-O visa early affect my expiration date?

The user transferred their Non-O visa to a new passport and is concerned about renewing it early, specifically whether they would lose days on their visa. Community responses indicate that applying for a one-year extension early does not result in losing days; the new expiration will always start from the current expiration date. Therefore, even if they renew on July 15, the extension would begin from the original expiration date of August 9.
