While you can often walk in for simple tasks, scheduling an appointment is recommended for complex disability filings. Please note that this office does not make final decisions on your claim, as that responsibility lies with the state disability determination service. Additionally, any necessary hearings are conducted by a separate office, not at this location.

Before you visit
Bring a valid government-issued photo ID and a detailed 15-year work history to your appointment. You should also provide a comprehensive list of all treating physicians, including their contact information and addresses. Bring any recent medical records, a current list of medications, and copies of any prior denial letters if you are reapplying. An attorney can help you prepare these documents to ensure your application is complete.
Avoid submitting an incomplete work history or failing to include contact information for all your recent healthcare providers. Many people also overlook the importance of documenting mental health conditions alongside physical impairments. Never sign forms without reading them thoroughly, as inaccuracies can lead to unnecessary delays in your application processing. Ensuring your records are complete before you arrive helps the claims representative process your file more efficiently.
Should you bring an attorney?
The application stage is the foundation of your entire disability case, yet many people navigate it without professional guidance. An attorney can help you identify gaps in your medical evidence and ensure your work history is accurately presented to the Social Security Administration. Most people who apply solo face significant hurdles if they are denied, making early legal preparation a strategic advantage. Request a free case review to understand how to strengthen your application before you submit it.

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. SSA routes appeals from the Wilmington field office to the hearing office below, per SSA's published service areas. The Wilmington field office holds your file at every appeal stage, but the substantive decisions happen further up the chain.
