Before you visit

To prepare for your visit, bring a valid government-issued photo ID and a detailed 15-year work history. You should also provide a comprehensive list of your treating physicians, including their contact information and addresses. Bring copies of your most recent medical records, a list of current medications, and any prior denial letters if you are reapplying. Expect your appointment to last between 45 and 90 minutes as a claims representative reviews your file.

Avoid common delays by ensuring your work history is complete and accurate for the last 15 years. Many people overlook the importance of providing recent medical records, which are essential for the state to evaluate your condition. Do not forget to mention all mental health conditions, as these are often as critical as physical impairments. Finally, never sign any SSA forms without reading them thoroughly to ensure all information is correct.

Should you bring an attorney?

The application stage is the foundation of your entire disability claim, yet many people navigate it without professional guidance. An attorney can help you gather the necessary evidence and ensure your application is complete, which may prevent unnecessary denials. If you are preparing for your first appointment, a free case review can help you understand your rights and the documentation required for a successful outcome.

If your SSDI claim moves to a hearing
