The expiration on the K1 visa is the date by which you must use it to enter the USA for the first time. Once you enter the USA on it, then it is no longer valid. It is a one time entry visa.

If you leave now, you will need the Advance Parole travel document to re-enter the USA. After you get a green card, you will use it for travel.
