You will find that applying for Social Security disability can be a lenghty process. There are three basic levels for an application: the Initial Claim, the Reconsideration, and the Hearing. There are waiting periods for each of these levels:
Initial Claim: Plan to wait 60 to 120 days for the decision on your Intial Claim.
Reconsideration: If you are denied on your initial claim, you will need to file an appeal called a Reconsideration. Plan to wait 60 to 90 days for the decision on your Reconsideration.
Hearing: If you are denied your Reconsideration, you will need to ask for a hearing before an administrative law judge. Plan to wait 14 to 18 months for a hearing.
