Perhaps you can help clarify what you mean by this statement? It seems you're saying that you previously went through the visa process with another person, and actually filed paperwork? Was this also a K1? What was the outcome? Was your partner approved? What sort of letter did you send to GZ two months ago? The short answer to your question, before you provide additional information, is YES. Previous filings can indeed affect other petitions.... Sorry for the confusion. Yes, I filed a K1 for my ex. I heard that she did received the P3, but that was after we seperated. I mailed a notarized withdraw letter to GZ two months ago. I included an explaination to USCIS when I filed the current K1.
