If you have any questions about international social security agreements, please contact the Office of International Social Security Programs at 410-965-3322 or 410-965-7306. However, do not call these numbers if you want to inquire about a right to an individual benefit. Select the country name from the following list to show the actual text of the agreement with that country. The term „totalization“ defines the second objective of the agreement. The ultimate goal is for a worker`s social benefits, whether paid in Switzerland or abroad, to be added up (or added up) so that the worker can, if eligible, withdraw these funds from a single government. If individuals are required to contribute to social security programs outside their home country, they are entitled to receive these benefits if they meet certain specifications set by the host government. The United States determines the totalization benefits a foreigner may receive, based on the length of the foreigner in the country and the length of his or her work in his or her country of origin. The United States has a threshold for the time it takes to work, to obtain comprehensive social security benefits and Medicare. With the countries with which it has a totalization agreement, the United States will rely on the threshold of the foreign period. If the combined amount exceeds the threshold, the United States then makes partial payments to the beneficiaries.
 Other features of U.S. law increase the likelihood that foreign workers will also face dual coverage in the United States. U.S. law provides mandatory social security for benefits paid as workers in the United States, regardless of the nationality or country of residence of the worker or employer, regardless of the length of residence of the worker in the United States. Unlike many other countries, the United States generally does not provide a guarantee exemption for non-resident foreign workers or workers who have been sent to work for a short period of time within their borders. This is why most foreign workers in the United States are covered by the U.S. program. Workers exempt from social security contributions under a totalization agreement must document their exemption by obtaining a country coverage certificate that continues to cover it.
The following lists reflect existing totalization agreements for other selected nations. Note: The social security totalization agreements with Korea, Quebec and Switzerland have not yet been approved by the Brazilian National Congress (which is therefore not in force). The detached house rule may apply if the U.S. employer transfers a worker to work at a foreign branch or in one of its foreign subsidiaries. However, in order for U.S. coverage to continue when a transferred employee works for a foreign subsidiary, the U.S. employer must have entered into a Section 3121 (l) agreement with the U.S. Treasury Department with respect to the foreign subsidiary. The provisions to eliminate dual coverage for workers are similar in all U.S. agreements. Each of them establishes a basic rule regarding the location of the employment of a workforce.
