Well you can't file for 2009 anymore the last day was April 15, 2013. You can still get a refund for 2010 and 2011. I did all three, and I'm expecting 5K but the IRS is too busy to send my refund right now it's been 8 weeks I have to wait four more. I was wondering how long was the wait for others?
Yeah I personally think you should go for professional help. Take your W2s amd the prove of filling for those years with your new social. That's all you will need.
