Anyone has experience as such ?
I just did it. The first thing the consulate demanded was the new version of my birth certificate available only from an USC office in Poland. I have no idea how to get it from here. I went to Poland in 2017 so it was really easy.
If you got married here, you will have to give them an apostille certified marriage certificate issued by the State of Illinois.
The consulate will demand your wife's presence several times. After the application was submitted, I had to wait for the PESEL number.
The most maddening thing was that there was no such thing as calling them and talking to a live person. Everything is by appointment, which means a trip to their office on Lake Shore Drive, and a 15-buck parking. Once inside, it goes fast.
