Introduction

For Republic of Korea, the Agreement covers old-age, survivors, and disability insurance coverage for all workers age 18-59 under the National Pension Act as well as contributions for the industrial accident program under the Industrial Accident Compensation Insurance Law. The Agreement does not cover civil servants, military personnel, or private school teachers.

Note: Workers exempted from Korean coverage by the Agreement pay no social security taxes for industrial accident insurance and generally cannot receive a benefit from it. If the Agreement exempts you from Korean coverage, you and your employer may wish to arrange for alternative benefit protection.

How benefits can be paid

If you have social security credits in both the United States and Korea, you may be eligible for benefits from one or both countries. If you meet all the basic requirements under one country’s system, you will get a regular benefit from that country. If you do not meet the basic requirements, the Agreement may help you qualify for a benefit as explained below.

  • Benefits from the United States - If you do not have enough work credits under the U.S. system to qualify for regular benefits, you may be able to qualify for a partial benefit from the United States based on both United States and Korean credits. However, to be eligible to have your Korean credits counted, you must have earned at least six credits (generally one and one-half years of work) under the U.S. system. If you already have enough credits under the U.S. system to qualify for a benefit, the U.S. cannot count your Korean credits.
  • Benefits from Korea - Social security credits from both countries can also be counted, when necessary, to meet the eligibility requirements for Korean benefits. To be eligible to have your United States and Korean credits counted, you must have at least 18 months of coverage credited under the Korean system.
