For Switzerland, the agreement includes old-age, old-age, survivors` and invalidity benefits. If you have any questions about international social security conventions, call the Social Security Administration`s Office of International Programs at 410-965-3322 or 410-965-7306. However, please do not call these numbers if you wish to inquire about an individual entitlement to benefits. Most U.S. agreements remove the dual coverage of autonomy by assigning coverage to the worker`s country of residence. For example, under the U.S.-Sweden agreement, a doubly covered independent U.S. citizen living in Sweden is only covered by the Swedish system and excluded from U.S. coverage. 12 In the meantime, the United States had also concluded an agreement with West Germany, which was also pending until the adoption of the 1977 amendments.
