ALERT: Your condition must significantly limit your ability to do basic work-related activities, such as lifting, standing, walking, sitting, or remembering – for at least 12 months. If it does not, the Social Security Administration will find that you do not have a qualifying disability. Going forward, we'll assume, hypothetically, that you've met the 12-month requirement at some point in the past. You may be eligible for a so-called "closed period" of disability if you were disabled for at least a 12-month period, and then recovered.
