L1B to H1B along with H4 possibility

[msunkar9]

Hi,

I am currently in US on L1B visa and my wife who is in India applied H1B through her Indian company and the VISA is approved.
I am not sure when my wife can travel to US as her company is a big IT company and they send people to US on seniority etc..

I am talking to few consultants in US and applying H1B this year.
My project in US will get over by June and I have to go back to India.

With the status/information as above, I have following questions assuming that my application is picked up in lottery:

1. What is the best way to come back to US
a. Apply for H4 and change to H1 after arriving in US?
b. Attend H1b visa interview directly?

2. What if my H1b VISA is denied? can I apply for H4 then and convert to H1b after arriving to US?

Either way I prefer to work/earn in US as early as possible.

Thanks
Sunkari
