Starting a Company on L1/L2 - Expert Help - Mr Subramanya

[muda]

Hi,
I was working in India for a well reputed company for few years and then my company offered my a position in US so I moved to US permanently with my family (L1 Visa for me and L2 for my Wife). Eventually my company will file for my green card (no time frame yet).

I plan to start my own company here without leaving my current company. Here are my queries regading the same...

1. Am I legally eligible to start my own company?
2. I live in State of Oregon. I recently heard that I can start my own company irrespective of my visa in some state like delavare, nevada. Can I start my company is other state?
3. If I start my own company, I believe I cannot work, but can I at least do management e.g. talking to client, customer etc.?

Thanks.
