International agreement coverage provisions may change the work test applied to a
U.S. totalization or nontotalization beneficiary. For example, the beneficiary's work
may have been subject to the Annual Earnings Test before the implementation of the
agreement. After the agreement takes effect, he may be subject to the Foreign Work
Test.
This is also true for self-employed persons, since self-employment is usually covered
by the country in which the self-employed person resides.
