Both me and my wife are in OPT ext., unfortunately I didn't win the lottery for H1b but she got it and it is approved already in June 2014. Can I apply Change of status for H4 before 1st of October when her h1b starts, do I need her H1b paystubs for my i539 form or HER current paystubs in OPT ext. is good for my application. My opt ext. expires on October 9th 2014.
