In most cases, a hearing with an Administrative Law Judge (ALJ) will be held. The amount of time varies from case to case depending on a number of factors, such as whether additional information is needed after the hearing. If new evidence is received after your hearing but prior to you receiving a decision, the ALJ will determine whether a supplemental hearing is necessary. After the ALJ renders a decision, Social Security strives to send you a detailed decision within 30 days.
