According the Social Security Administration, the average wait for a hearing to be held at one of North Carolina’s ODARs for the month of June 2015 was:

Charlotte – 18 months.

Greensboro – 18 months.

Fayetteville – 18 months.

Raleigh – 16 months.

My experience is that the wait times on average are longer by 2 months for each office.
