Thanks for your reply.
So when we have to apply for GC she has to come to US and then she can leave US and when we get notice for FP then she can again come back give her FP and leave country?
---------once she file I-485 she should go out after she gets herI-485 filing reciept from USCIS.She should do her FP in US. Fingerprint notice is sent 25-30 days advance of FP date.
Can she alone do this at the US consulate in India?
---------------what is to be done at US consulate in India????
What about medical examination do we have to do it at the time of filing GC?
------why are you writing the word "GC"? You should write I-485 and I-485 is the last step of GC filing or AOS filing. one need to compleate medicals in US and medicals are sent with I-485.
