I have an O-1. Still didn't help me get a Green Card!

If you don't mind answering. For an O-1, do you really have to be a Nobel prize winner? or a Phd or a lot of work experience help?

No, you just need great documentation of your accomplishments and an excellent lawyer who knows how to handle the process. $$ It helps if you have done original work, and if a well known/internationally famous person in your field (or several) vouches for you in the form of a recommendation letter.

Try yearly lottery. You have higher chance! ;-)

GC lottery depends on where you were born and countries with a certain amount of immigration do not get to participate in the lottery. India almost certainly is one of those countries that doesn't get to participate. Others are Mexico, Canada, probably China and Philippines too.
