I and my wife got 2nd time finger print notices. But my wife is in India and cannot make FP appointment due to family issues. I am the primary applicant and my PD is current(EB2-Dec2004-India).

(1)Do you think any issue will raise on my I-485 application if my wife fails to give her FPs and I have given mine? Do uscis consider both 485 applications together since both are in the same family and filed together? Is there any dependency?
(2)Can USCIS process my 485 separately and send GC to me if my 485 application is approved and my wife 485 is in pending status?
(3) Is there any chance my wife can get approval for her 485 without giving 2nd time FPs though she received FP notice?
