H4 to F1 COS. Proof of ability to pay

[venad]

Hi,
I am H1 and my wife is on H4. She got admission to a university and we are considering changing her status to F1.
My question:
1. What documents we need to submit or what documents COS to F1 applicants usually submit as proof of "ability to pay for your studies and support yourself".?

2. I am thinking, her bank statements, my pay stubs, a letter from my employer, are these documents enough?

Thank you for your time.
Any reply greatly appreciated.

Yes, those are good enough. Make sure the bank account has $ for one year worth of fees - 2 semesters at the least.
