her B2 application would have been scrutinized whether or not the expedite was sent. Her B2 application might be denied as she shows immigrant intentions, but it never hurts to try (if you are willing). I have seen cases where applicants are given the B2 with a pending i130, just ensure she has good reasoning, length of stay and strong ties to the home country shes from..

her B2 application may be denied, considering you mention on the application that an immigration petition has been filed on her behalf. b2 visa is for non-immigrant purpose, in your case Embassy officer would know that the intention is to immigrate and may deny b2 visa

yes I agree with J J and optimistic bird, now an immigration visa is pending it will be difficult to get a B2 tourist visa. B2 visas are solely for tourist purposes only with no intent of residing in the US. The I130 application has already shown that she wants to live in the US. Its a difficult time for us all with this unknown waiting time.

The intention is not to immigrate with B2 visa as she still have things back home to take care of, I was wondering if that denied expedite request would be asked about or effect the B2 visa interview.

no, it wouldn’t be asked about as it has no relation to her B2 Application. But as i said, they will still scrutinze her as she will have already showed immigrant intentions… ensure you have a good reason for whatever the officer asks you as that will ultimately decide the decision. she might even be given a one time entry just to visit you once, it all depends.
