Under what circumstances can a non-resident of South Carolina carry a concealed weapon in the state?

A non-resident of South Carolina can carry a concealed weapon in the state if they possess a valid concealed carry permit from their home state that South Carolina recognizes. This means that they have gone through the necessary background checks and training in their home state and have met the requirements to carry a concealed weapon. Options B and C are incorrect as they only pertain to specific situations and do not apply to all non-residents.
