Hello every body

I am planning to apply to EB2 for a green card.
Some friends told me that you better hire a good damn lawyer to prepare you file properly, and increases your chances in getting the card.
Others say that lawyers don't do anything besides organizing your paper work, and make sure you have all the necessary documents, and submit you file to the gov agencies, and they will take a big amount of money
For that. They don't give your file any legal support.
You can save you money, by buying a kit for 50 or 60 bucks, and do it yourself.

So, I am perplexed and confused. What to do, and which option is better, attorney, or do-it myself??

Any advices, past experiences is appreciated.

You should hire an experienced attorney. NIW's are more difficult now than ever. Unless you are very familiar with current the case law, NYSDOT. Ask your colleagues and other professional contacts for referrals or check with AILA or your state bar referral program. Good luck.
