Whether re-entry is possible if I left Korea for the U.S. while owing debt there in the past

Hello. I previously lived in the U.S. and had credit card debt at the time, which I didn’t properly resolve before hastily returning to Korea.

Recently, my company said they’d send me on a business trip to the U.S., and this issue suddenly came to mind. I’d like to know if this could cause a problem when I enter the U.S.
