Form I-797C, Notice of Action

[masha4kalinina]

Hi everyone! I just received my forms I-797C, a notice of action for forms I-485, I-765, and I-131. It just says that my applications have been received by their office and are in process. I don't have any Alien Number or USCIS Account Number there yet and I was trying to add a paper-filed case to my account but it requested an Online Access Code which I don't see on my I-797C notices. So, in this case, does it mean that I should expect one more letter from USCIS with my USCIS Account Number and Access Code?
Thank you!
