Article 4.4 eliminates dual coverage and contributions with respect to self-employment. It provides that self-employed Korean residents will be covered only under Korean laws and that self-employed U.S. residents will be covered only under U.S. laws. This provision will primarily affect self-employed U.S. citizens who work and reside in Korea. In the absence of an agreement, such persons would be covered under Korean law because they live and work in Korea, and would also be covered under U.S. law because they are U.S. citizens.
