My wife's H 1 B I 94 Expired on 08/31/2012. Her employer filed H 1 B extension having receipt n 08/ 27/2012. She got RFE in october having to reply before 01/25/2013. Now can she apply for F 2 prior to 01/25/2013 considering there are almost no chance that employer would respond to the RFE or even he does there are chances of getting denial what are the chances of getting COS approved for H1 b to F 2 ?. What happens if in case she files I 539 and her H1 B gets denied? . And after that her COS from H1 B to F 2 gets denied.?I am on Student VISA F 1 and Have been lawfully maintaining the status. And I have never been out of statu, no misconducts and have clear school records.
