EB3 Green Card Processing Time

[astonm]

Hello,

I am on H1-B visa which will expire in September 2012. I have been working at my company in New York state for last 3 years and I am thinking of asking my employers to process my EB3 Green Card.

A brief background about me:

a) I am an Indian citizen

b) I did my undergraduate here in USA - been here since 2003

c) Graduated in bachelors in 2008 and I have been working at the same company since

d) I am also doing my Masters (part-time), so expected graduation is Summer 2012.

My dilemma is, I want to find another job (and company) after my Masters (quite possible around fall 2012) or later. But I am still in this company for over a year, so I am wondering if I should ask my employers to sponsor me for an EB3 green card. So essentially my questions are:

a) If my employer starts processing now, how long it may take for me to finally get my green card?

b) Once I get my green card, can I find another company to work for?

c) Can I still find another company to work for when the green card process is going on? The second company can reapply for my green card or I can work for them on H1-B.

d) how much it will cost my company to process my green card?
