In addition to the minimum coverage requirements, a recent coverage requirement applies
            to disability and survivors benefits. The worker or deceased worker must have had
            current coverage under the Korean system at the time of disability or death. The Agreement
            provides that a worker will be deemed to meet the current coverage requirement if
            the worker:
         
         
            - 
               
                  • 
                     Was insured for a U.S. Social Security benefit at disability onset or death; or 
 
 
- 
               
                  • 
                     Has credit for at least four quarters of coverage (QCs) in the 8-quarter period ending
                        with the calendar quarter of disability onset or death.
