Unfortunately, Social Security disability claimants typically have to wait one to two months after approval before they will see their first Social Security Disability monthly payment. In most cases, it will take even longer for you to receive your back pay. Fortunately, any time that passes between approval and your first benefit payment should be reflected in your back pay. If you haven’t started receiving your Social Security Disability benefits within 90 days of approval, contact the SSA. For faster results, have your Social Security Disability lawyer contact the SSA.
