After u sign up for disabilty how long does it take before u will hear from them about your disabilty how long will it take before u will be able to hear from them about it

The length of time it takes to receive a decision on your disability claim is from 3 to 5 months. It can vary depending on several factors, but primarily on:

the nature of your disability;
how quickly we obtain medical evidence from your doctor or other medical source;
whether it is necessary to send you for a medical examination in order to obtain evidence to support your claim; and
If your claim is randomly selected for quality assurance review of the decision.

The info above came from the FAQ on the Social security site.
