My first application was denied. Think that's fairly typical.
I got a lawyer who only charged if I got SS. The lawyer got all the records together, filled out the forms and set up the date with the judge. Using a lawyer, I did not have to wait long.
To find a lawyer versed in Social Security you can call your local Bar Asso. (listed in yellow pages).
I strongly recommend you get a lawyer and let him/her shuffle through all the paperwork.
