My wife will have her interview on Jul , 9 for CR1 route. But today I got an email in which they said they approved my K3 application on Jul, 3. What can I do with this? Do I have to make a cancellation for this K3 if my wife pass interview. And if we got problem with CR1's interview, may I continues with the process of K3 and have interview for K3?. Anyone has the situation like this. I need some advices. Thank you.

I think the I-129 will automatically cancel out in favor of the I-130 since that is the one that arrived first.
