Before you visit

Arrive at your appointment with a government-issued photo ID and a detailed 15-year work history. You should also bring a comprehensive list of your treating providers, including their names and addresses, along with any recent medical records or test results. If you have received prior denial notices, include those in your folder to help the representative understand your claim history. Appointments typically last between 45 and 90 minutes as staff verify your documentation.

You may delay your claim by failing to provide a complete 15-year work history or missing recent medical records from your primary care providers. Forgetting to disclose mental-health conditions or failing to review forms for accuracy before signing can also lead to unnecessary processing hurdles. Ensure you have all required documentation organized before your visit to avoid multiple trips to the office.

Should you bring an attorney?

The application stage is the foundation of your entire disability claim, and errors made here can be difficult to correct later. An attorney can help you gather the necessary medical evidence and ensure your application accurately reflects your limitations. Most people who apply without legal guidance find the process overwhelming, but a free case review can clarify your options before you submit your paperwork.
