We should hear from them within three weeks of getting our NOA2. Whether that's three weeks after the NOA2 date (March 4th) or three weeks after Foofer received the I-797 through the mail (March 19th) - I'm not sure. I am sure that using the word "mail" instead of "post" will take some getting used to.
So, for the moment, we await news from Portsmouth, NH.
