Their Sang O class boats have a range of 1,500 miles which are their longest range indigenous small subs.

However their is another way too, look at this photo:

This is a captured North Korean 'P-4' class small submarine. Notice her bow? That eye bolt like thing? Its likely that is for towing the sub long distances using a trawler or freighter. A North Korea cargo ship could tow her to the US West coast and release her once its in range then pick her up later.
