how the process works for SSDI in Illinois
To explore for Social Security Disability Insurance (SSDI) in Illinois, you must file with the Social Security Administration—not with the state. You can start your process online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. Illinois has 47 Social Security field offices statewide, and staff there can walk you through the process on the spot if you prefer not to do it at home.
The process itself takes 15 to 30 minutes to complete, but the real work is gathering the documents Social Security will ask for. You will need your birth certificate, proof of citizenship or legal residency, tax returns or W-2s from the past two years, and medical records showing your condition and treatment. The entire process from submission to a decision typically takes three to six months, though cases involving appeals can stretch much longer.
Key Takeaways
- You explore directly to the Social Security Administration, not to Illinois, using ssa.gov, a phone call to 1-800-772-1213, or an in-person visit to one of 47 Illinois field offices.
- You will need your birth certificate, proof of citizenship, tax returns from the past two years, and medical records documenting your condition and all treatment you have received.
- Social Security will request additional medical records directly from your doctors and hospitals, so providing their contact information on your process speeds up the process.
- If Social Security denies your process, you have 60 days to file a written request for reconsideration, which is a separate review by a different examiner.
- Illinois residents can contact the Disability information Services office in Chicago if they have questions about their case status, but decisions are made by Social Security, not the state.
Starting Your process Online, by Phone, or In Person
The fastest way to begin is online at ssa.gov/applyfordisability. You create a my Social Security account, answer questions about your medical condition and work history, and upload documents directly. The system saves your progress, so you can stop and return later. Once you submit, Social Security sends you a confirmation number and tells you what happens next.
If you prefer to explore by phone, call 1-800-772-1213 between 7 a.m. and 7 p.m. Monday through Friday. A representative will ask the same questions as the online form and can answer questions as you go. You will still need to mail or upload your documents afterward, but the representative can tell you exactly what to send.
To explore in person, find your nearest Illinois Social Security office at ssa.gov/locator or call 1-800-772-1213 for the address. Bring your original birth certificate, proof of citizenship (passport, naturalization papers, or state ID), and any medical records you have on hand. The office staff will help you fill out the form and can scan documents on the spot.
Documents You Must Gather Before You explore
Social Security will ask for the same core set of documents regardless of how you explore. Have these ready before you start:
- Birth certificate — original or certified copy
- Proof of citizenship or legal residency — U.S. passport, naturalization certificate, state ID, or driver's license
- Social Security card — or a record of your number
- Tax returns or W-2s — from the past two years, to show your work history and earnings
- Medical records — names and addresses of all doctors, hospitals, and clinics that have treated you for your condition
- List of medications — names and dosages of all prescriptions you currently take
You do not need to collect all your medical records yourself. When you list your doctors and hospitals on the process, Social Security will request those records directly. However, if you have recent test results, imaging, or specialist reports, uploading them with your process can speed up the review.
What Social Security Examines During Review
After you submit your process, Social Security sends it to the Disability information Services (DDS) office in Chicago. That office reviews your medical records to determine whether your condition meets Social Security's definition of disability: you cannot work due to a medical condition that is expected to last at least 12 months or result in death.
The examiner will look at your medical evidence first. They need documentation that shows your diagnosis, test results, imaging, and how your condition limits your ability to work. If your records are incomplete, DDS will request more from your doctors. This is the most common reason applications take longer than three months.
The examiner also considers your age, education, and work history. Younger applicants face a higher standard of proof because Social Security assumes they have more time to retrain for different work. Older applicants (typically 55 and up) may be found disabled with less severe conditions if they cannot transition to other jobs.
Timeline: What to Expect Month by Month
| When | What Happens |
|---|---|
| Week 1 after submission | Social Security sends you a confirmation letter with your case number and tells you what documents to send. |
| Weeks 2–4 | DDS requests medical records from your doctors and hospitals. You may receive requests for additional information. |
| Weeks 4–12 | An examiner reviews your medical evidence and work history. DDS may contact your doctors for clarification. |
| Month 3–4 | DDS makes a decision and mails you a notice. The notice explains whether you were found disabled and includes information about benefits or appeal rights. |
This timeline assumes your medical records are complete and your case does not require a consultative examination (a medical exam Social Security orders when records are unclear). Cases involving appeals or additional medical evidence can take six months or longer.
If Social Security Denies Your process
About 65 to 70 percent of initial applications are denied. A denial does not mean you cannot receive SSDI—it means the examiner did not find enough medical evidence that your condition meets Social Security's definition of disability at that time.
You have 60 days from the date on your denial letter to file a Request for Reconsideration. This is a second review by a different examiner who looks at your case from the beginning. You can submit new medical evidence, updated records from your doctors, or additional information about how your condition affects your work. Mail your request to the DDS office in Chicago or submit it online through your my Social Security account.
If reconsideration is also denied, you can request a hearing before an Administrative Law Judge. This process takes longer—typically 12 to 18 months—but a judge can weigh your testimony and medical evidence in a more detailed way than an examiner can. You may want to consult with a disability representative or attorney at this stage, though it is not required.
Illinois-Specific Resources and Support
Illinois does not run SSDI itself, but the state offers resources to help you understand the process. The Illinois Department of Human Services operates a Benefits Outreach and Enrollment program that can answer questions about SSDI and other benefits. You can reach them at 1-877-411-4357.
If you need help filling out your process or gathering documents, contact your local Area Agency on Aging (even if you are not yet 60—they serve people with disabilities too) or a legal aid organization. Many offer free help with SSDI applications. The Legal Aid Society of Metropolitan Chicago, Prairie State Legal Services, and Land of Lincoln Legal information Foundation all have staff who can guide you through the process at no cost if you meet income limits.
You can also work with a Social Security representative payee or attorney who specializes in disability claims. Representatives charge a fee only if you win your case, and Social Security must approve the fee (usually 25 percent of your back pay, up to $6,000). An attorney can represent you at any stage, including appeals.
Frequently Asked Questions
Can I work while my SSDI process is being reviewed?
Yes. Working does not disqualify you from SSDI. However, if you earn more than $1,550 per month (in 2024), Social Security may conclude you can work and deny your claim. Keep records of your earnings and any work limitations you experience, as these can support your case.
What if I do not have all my medical records when I explore?
You do not need to have them before you submit. Provide the names and addresses of your doctors and hospitals, and Social Security will request the records directly. However, the review will take longer while Social Security waits for those records to arrive.
Do I need a lawyer to explore for SSDI in Illinois?
No. You can explore on your own and many people do. A representative or attorney is most useful if your process is denied and you are preparing for reconsideration or a hearing, because they know what evidence Social Security looks for and how to present your case effectively.
How much will I receive in SSDI benefits if I am found disabled?
Your benefit amount is based on your lifetime earnings record, not on your medical condition or financial need. The average SSDI payment in 2024 is around $1,550 per month, but yours may be higher or lower depending on your work history. Social Security will tell you the exact amount in your approval letter.
What happens to my process if I move out of Illinois?
Your process continues with the DDS office that is reviewing it. You do not need to restart or reapply. Update your address with Social Security so they can mail you notices and decisions at your new location.
