Provided she qualifies and there are no factors to affect the process it will take 3 or 4 months if adjusting through the USCIS. If you are going through the courts it will depend on the court docket.
I agree with Ms. Mulder: if there are no complications.... However, I would estimate the timeline a bit longer right now and part of that is just based on my conservative nature on things like this.
I would try and agree with Attorney Mulder's optimistic assessment. I am a bit skeptical on the timing but who knows, maybe USCIS will be very efficient in your case.
