I am on H1 with X company and my wife is on H1 with Y company[MNC]. My wife had taken extended maternity leave for period 6months as per company policy which was an unpaid leave and HR approved for that same along with normal 3 months maternity leave[Paid leave] . Now i am thinking to convert my wife’s status from H1 to H4 by applying COS through my company. The question is will USCIS accepts the pay stubs,I797 that she got before her extended maternity leave[I think this is called her Longterm disability] ? Does she have to take any additional documents from her company[MNC]. She has valid I797. Please suggest me if we will face any issues before approving COS.
