Most states have reciprocal agreements with each other or otherwise have decided to share traffic violation convictions that were received out of state back to the licensing state of the driver who received the citation. This can be for a minor offense such as a speeding ticket or a major offense such as a DUI. If you were convicted of a DUI in the state of North Carolina, your home state of South Carolina has a reciprocal agreement with many other states, including North Carolina, to share driver information.  You will likely have to abide by South Carolina's DUI requirements.
