how long for first payment after receiving disability approval letter
When Your Benefits Start. If your application is approved, your first Social Security benefit will be paid for the sixth full month after the date we find that your disability began. For example, if your disability began on June 15, 2015, your first benefit would be paid for the month of December 2015, the sixth full month of disability. Social Security benefits are paid in the month following the month for which they're due.
