This book contains the Agreements on Social Security between the United States and Iceland, Uruguay and the Republic of Slovenia. The Agreements are similar in objective and content to the social security totalization agreements already in force with other leading economic partners in Europe and elsewhere, including Australia, Canada, Chile, Japan, Norway, the Republic of Korea, and Switzerland. Such bilateral agreements provide for limited coordination between the United States and foreign social security systems to eliminate dual social security coverage and taxation and to help prevent the loss of benefit protection that can occur when workers divide their careers between two countries.
