When Should You Apply for SSD?
The SSA recommends beginning your application for SSDI or SSI benefits as soon as you learn that you are disabled. The application process can be time-consuming, and the SSA can take three to five months or more to review the application once it is submitted. It could take even longer to process if your application lacks critical evidence or contains errors.
Then, assuming the SSA approves your application, you typically need to wait an additional five months before receiving disability benefits. You should receive your first benefit payment in the sixth full month after the onset of your disability. If you are disabled due to amyotrophic lateral sclerosis (ALS), however, you may be able to forgo this waiting period if your benefits are approved on or after July 23, 2020.
