H4 to H1 visa processing

[meetsugan]

Hi,

I am currently on H4 in the US which is valid till Jun 2012. I am applying for H1 premium processing this April 2012. My spouse's H1 and my H4 extension are not yet done by my Spouse's employer. I have the following questions

1. Can I apply for H4 to H1 change of status, since my current H4 is valid only till June?

or should I go for a fresh H1? which is the best way to do H1 processing in my case.

2. After H1 approval, can i apply for H4 extn, to stay in US until my H1 effective date(which will be Oct 1).

Please help!
