My question involves a driver's license issued by the State of: North Carolina

Since I'm now living in the Grand Duchy of Luxembourg, I had to switch my North Carolina license for a Luxembourgish license, which I did back in September. (If I didn't do it within a year of entry, my NC license would become void in Luxembourg and I'd have to do the licensing examinations here, but that's a separate story.) Part of the process required me to surrender my license to the Luxembourgish authorities who would then return it to the issuing authority, which I did do; since I surrendered the license, I thought that'd be all.

Out of curiosity, though, I looked up my driving record online on the NCDOT website... and it still lists my NC license status as being "Active" and the system allows me to order a duplicate! (And this is almost three months after I gave up the NC license.)

So, the question is, since I'm going back to the US for Christmas vacation and will probably be doing a nonzero amount of driving while I'm there, would I need to order a duplicate of the NC license to use there, or would I be fine to just keep and use my Luxembourgish license?
