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
was insured for a U.S. Social Security benefit at disability onset or death, or
has credit for at least 4 quarters of coverage (QCs) in the 8-quarter period ending
with the calendar quarter of disability onset or death.
