moving to US
tarouter: I think patio11 has some excellent advice. On top of that, why not partner with someone who is already in US? That way you can have benefits of (one co-founder) being in India and benefits of (other co-founder) being in US. 
I live in US and I would love to explore options to partner someone in India. Being Indian myself, I know that there are some business models which have very good potential and require presence in India and US both. e.g. selling westerns clothes (with traditional india designs) made in india over web. 
I have other ideas too, some geeky, some not-so-geeky. If you are interested, send me a one liner on 'my HN user name' at gmail dot com. we can share some ideas and may be collaborate if we hit it off.
