Right, I'm in the same boat. I went out of my way to do everything as legal as possible. I could have easily stayed in the US and do AOS from my J1 visa, but instead I returned to my home country and applied for a CR1. I helped a friend with her green card, she lied to the immigration officer when getting a B2 knowing she wanted to marry a US citizen, stay and work illegally in the US. She got her GC without an interview at all. I am very happy for her, but it would be just absurd they interview me for my ROC, but they don't interview people who worked illegally and overstayed their visas for years. I send them over 300 pages of evidence that me and my husband have every aspect of our life connected and joint, so I just find it hard to believe that in less than a couple of days they looked over all that evidence and decided my case is a risk, but you never really know with them.
