I m familiar with NIW process as that was my fall back plan. Infact I was in process when I found out I was selected for DV lottery (wasted close to $6000 in attorney fees for a process which I didn't even use). Process is quite lengthy as it involves getting recommendation letters, preparing a petition, writing a research summary. Then you have to apply for I140 to get the exception followed by I485. If you are lucky you will get u r I140 approved with in 3 months if not it will take around a year. Alternatively you can concurrently file i140 and i485 which might be a route you should prefer if this is possible. What I can do is if you are in my field of study I can give you a recommendation letter (independent one) why don't you PM me regarding u r field.
Cool, thanks for the info and offering your help. I'll send you a message.
