I haven't heard of them being sent together. They're usually in separate mail as far as I know.

Go to this link: https://ceciva.uscis.gov/Alme/
At the top right, click on "Ask a Question" with a woman's face. When the chatbox comes up in the bottom right of your screen, type "infopass". Then, when prompted, type or click "Make an infopass appointment". When asked for reason for appointment, type again "Make an infopass appointment".
You should then be connected to a live person who will help you find your receipt number and answer questions to the best of their ability. I got my receipt code from them. I also did not get any notifications prior to doing this. After you get the code, you can check the status online via https://egov.uscis.gov/casestatus/landing.do and find out what's going on with it.
Hope this helps and doesn't come off too detailed, trying to assist 'cuz I know how it feels. 😎 BTW, best time to do it is in the early hours of the day, while everyone is at work, etc.
