Yes, she can apply using 245(k) since 60 days is less than 180 days.
Yes, she can apply using 245(k) since 60 days is less than 180 days, otherwise, she can apply using 245(i) - more than 180 days. But talk to her own lawyer. The question is: Is she still with her primary applicant (husband) who is applying for his 485 and filing his wife's 485 for his wife?
If her primary applicant (husband) already used 245(k) for himself, his wife is eligible even though his wife's status is out of status. I have heard of it somewhere, but not sure about this. Just tell her and her husband to talk to their own lawyer.
