Changed my passport since applying for K1

[unstrung 0]

We applied for the K1 and recently received our NOA2. My question is, since we applied, i have had my passport renewed, so i got a new passport and the passport number is now changed, so it differs from the number that appears on the forms we sent out. Must i inform USCIS of this change? Is there a form of some sort i must now will out?

It would help to know if you are the USC or the Canadian fiance.

I'd call the DOS to be certain but i'm going to assume it will be taken care of at the interview.

We both use this login, but i am speaking as the canadian fiance right now

Now your package will be sent to the Consulate in either Montreal or Vancouver. When sending back Package 3, you might want to include a letter saying that you've recently updated your passport, and type out your new passport number. I don't know that they have to have it prior to the interview or not, but this would probably be a good time to let them know.
