Under the original 1980 agreement, no U.S. QCs could be granted for Swiss coverage
based on noncontributory credits (i.e., for the nonworking wife of a worker who is
covered under the Swiss system). However, the supplementary agreement, effective 10/1/89,
provides that U.S. QCs will be granted for Swiss noncontributory credits.
SSA will credit U.S. QCs for Swiss noncontributory credits (in the same manner as
described in GN 01709.120B.) where necessary to establish entitlement to Totalization benefits for months 10/89
and later. Although noncontributory credits before that date may be taken into account,
the earliest possible month of entitlement to Totalization benefits where such credits
must be counted to establish U.S. insured status is 10/89.
