Hold in there...be very careful since that can go in a thin line...if you have been waiting 5 months already in VSC...your waiting to be still with your wife "as married" is over 6 months (check the time on VSC of people over here, myself included), think about it. If you think you can do it...is your call.
Be aware that family law (divorce/marriage/child custody, etc) varies by State and the requirements differs and that can play a decisive point.
You can be in a worse problem if you are actually separated or no longer in a marital relationship, and then call for an interview and she refuse to go. Even interviews are not that common they do happen.
Since you say that "we wanna file for divorce" looks that is mostly a mutual thing...you two should think about the cons and pros and if the matter for why you want to divorce there is no really a solution for it.
Good luck.
