My question is about 1-797 Notice of Action

Hi, You will next receive a letter from the NVC letting you know one of two things 1. Either that there is no visa number available and that they will keep the approved application on file (This is the most likely scenario as this is a seriously backloged category) OR 2. A fee bill for visa fees and instructions on how to pay Be sure he remains unmarried. When you become a citizen, you will want to write to the NVC with a copy of the NVC letter showing the case number and a copy of your naturalization certificate. This communication is intended as general information and not specific legal advice, and this communication does not create an attorney-client relationship. Consultation with an experienced competent immigration attorney is often the best way to address the complexities of individual immigration issues.
