Article 6 contains rules for determining U.S. benefit eligibility and amounts in the case of people who have periods of Social Security coverage in Chile and at least six quarters of coverage in the United States, but who do not have enough U.S. coverage to qualify for U.S. benefits. In such cases, the Social Security Administration, in accordance with Article 6.1, will take into account any periods of coverage credited under Chilean laws insofar as these periods do not coincide with quarters of coverage already credited under U.S. laws.
