EB1 Green Card

I have been working as part of a research group in a bank over the last 4 years. I am a ranked research analyst on wall street and My work has been quoted in popular media, our research has been uploaded to government organisation webpages and have been referenced by government officials. I have also published 50+ articles over the last 2 yrs. The catch is that I may be moving from a research role to a trading role (my primary function will not be research). What do you think my changes are for EB-1 (b) and would this change totally eliminate me from applying?

If my company applies EB1 this month (Aug, 09), and everything goes well, by when should I expect my green card? What are the disadvantages of applying under EB1?

I was married 9 years ago and am now getting divorced. My wife’s green card was granted on the basis of my EB1 filing. To ensure that her GC remains valid, is there a period of time that we need to wait after the GC approval date before filing for divorce? If there’s no such requirement, is it okay to state that we separated over a year ago (prior to the GC approval) on the divorce papers?

My company filed an EB1 in 2005 for me; my wife was part of the same filing. I received my Green Card in April 06 but my wife’s application is still pending. We contact the USCIS every 6 month and each time they send a standard letter telling us to check back in 6 months. Actually, one time the letter said check back in 3 months but the last letter went back to the normal 6 months. She went for fingerprinting in 2006 and 2007 but we have not received any requests since then. Is there anything that we can do?

My company applied to change my status from L1B to L1A at the same time as filing my GC application. It was approved and the GC only took about 5 months

Does a person with EB1 Extraordinary Ability category I 140 approved , require employment letter during I-485 filing ?

I want to know whether our federal bank (reserve bank of India) is allowing this US $500,000.00 for investment in U.S.A. Then I will ask some more questions like whether it is easiest way to get green card and whether our money is safe in investment (in the regional projects) and the total expenses upto green card release level (apart from us$500,000.00)

My 6 year period of H1b visa expires in Dec 2010 and my labor application is still pending for approval. It was filed in February 2009. Am I eligible to apply for a visa extension , if so when should I apply for that? I assume I still have time.
