K-1 visa application with old I-130 petition pending

[soon2batexan 3]

Just wanted to get my fellow users thoughts on something.

To make a long story short, my K-1 visa interview is taking place in Vancouver in a couple weeks. I've been assigned an A#, etc etc.

My Mom is an American citizen and filed an I-130 petition way back in 2006 when she and my Dad were first considering a move to the U.S. We were told by the Montreal Consulate that because I was over 21 at the time of filing, I'd likely be in line for 7 - 9 years until my priority date became "current".

Since that time, my parents relocated to the US two years ago and I have remained here in Canada living and working. Over the course of visiting my parents in Texas, I met my Fiancé. We filed the I-129F back in April, and we've been extremely blessed in that everything has moved along quickly thus far. I have a friend who is a lawyer, and while she said the CO may or may not ask about the I-130 Petition for Adult Son/Daughter filed over 4 years ago by my citizen Mother, my friend doesn't see any reason for concern given the length of time that has passed since that other petition was filed and the fact that I've always done everything legally (didn't overstay when visiting, filed documents to enter legally as a Fiancée, etc) and will be immigrating from Canada (which I gather is a country with a relatively low fraud rate). Plus they are entirely different petition types filed by different petitioners for different reasons.

My US Citizen Fiancé will be attending the visa interview with me and we're taking lots of proof of our ongoing relationship (boarding passes, e-mails, photos, signed statements confirming our intent to marry, etc), but I'm just wondering if any has any advise/experience with this sort of situation.

If they ask about it I intend to answer honestly that my parents filed the I-130 to see if I could join them and when we found out I'd have years to wait, I was content to remain in Canada living, working and waiting to see if anything would come to the petition someday. That is, until I met my Fiancé...I adore him and now I can hardly wait to move and get married!
