F-1 visa stamp, H-4 pending

Question details

I'm on H1B working in USA. My visa was expiring in May, so my company applied for H1B and H4 (for my wife) extension in April.
In May 1st week, my wife got admission & assistantship in one of the university. She returned to India on May 20th and she got her F1 visa stamped from India.

Now we are very much concerned that what will happen to my H1 and her H4?

1) Since she has F1, will it affect H1/H4 processing?
2) Do we have to apply for H4 withdrawal in order to maintain her status as F1 ? If so, is it possible for you to apply withdrawal on behalf of us? What is the fee you charge for the same?
3) Is it possible to have F1 and H4 both together at the same time?
4) Since my Employer is a large company and they have filed H1-H4 on behalf of us, is it possible for an outside agency to file H4 withdrawal? And will the H4 withdrawal application affect my H1 visa extension application?

ANSWER

1. H-4 is her personal application. All she needs to do is send a letter to USCIS stating "I hereby withdraw my application for H-4." Attach a copy of the fee receipt for H-4 application that comes from USCIS. I see no need for you spend money on legal fees, but that is your choice.

2. If nothing else works and she does get the H-4 approval, just have her step outside USA and reenter on F-1 visa and get a new I-94 from CBP at the airport.

3. Generally speaking, no.

4. Let your employer know. They should be able to withdraw for you. If not, do it yourself as I have suggested.
