Eligibility of H4 Extension if COS to F1 in India

[user2018]

Hi,

My spouse has her H4 extension in progress but the current processing time is 12-15 months (July 2019). In the meanwhile, my wife is planning to join a masters program on F1. The catch is that the H4 COS to F1 is a 12-15 month wait itself during which my wife would be unable to work on CPT which is a course requirement. We are also travelling to our home country this January and plan to get our visa stamped (H1B & F1).

1) If my spouse's F1 visa is rejected for any reason, does that make her H4 extension stay illegal and out of status? Will it have any impact on her H4 visa stamping?

2) If F1 is rejected, how soon can she apply for H4 on my approved I797 ?

 

Any help will be valuable. Thanks.
