Before you visit
Bring a valid government-issued photo ID and your work history to your appointment. You should also provide a complete list of your treating physicians with their contact information, recent medical records, and a current list of all medications. If you have received any prior denial letters, include those in your folder. Expect your interview with a claims representative to last between 45 and 90 minutes.
Avoid submitting an incomplete work history or failing to provide recent medical records from all your treating providers. Many people also neglect to mention mental health conditions, which are critical to a complete disability profile. Never sign forms without reading them thoroughly, as inaccuracies can lead to significant processing delays. Ensure all contact information for your doctors is up to date before you arrive.
Working while you apply? Check how much you can earn on SSDI this year — SSA's earnings limit is the first thing it looks at.
Was your claim denied? Decode the letter — what the sentence means, what to file, and by when.
Should you bring an attorney?
Applying for disability is a complex process where the evidence gathered at the initial stage defines your entire appeal record. Most people who apply without professional guidance find themselves facing unnecessary denials. An attorney can help you understand your options and ensure your application is as strong as possible from day one.

If your SSDI claim moves to a hearing
About two-thirds of initial SSDI applications nationwide are denied. If yours is, your case moves to a hearing before an Administrative Law Judge at one of the regional hearing offices that handles appeals from Alton. The Alton field office holds your file at every appeal stage, but the substantive decisions happen further up the chain.
