Welcome to the board and congrats on your happiness. I'm filing CR-1 and CR-2 so there are differences in the process from your K1, K2 filing. That said there are some similarities too. From what I understand though, since the daughter is over 18, the K filing is the only way she will be able to accompany her mom the the USA. Others will correct me if this is wrong. There are others on the board that are doing what you are, so you will get good advice here. I didn't need to file a G325a for my daughter, but she is under 18, so not sure about that. If you paid an agency to be introduced, you may have some IMBRA (International Marriage Broker) issues, again not sure what they might be, I'm just trying to identify areas you may need to address over the course of your visa journey. The CCP family member is not an issue, I think every family in China probably has some members. Like Dan said, only an issue if your fiance was a membber and that has been overcome many times. Your initial filing is with USCIS, so the consulate won't have muuch info regarding that, again like Dan said, you'll only deal with the consulate at the interview stage. Good luck and keep reading, it's only just begun.
