The Agreement with Romania became effective on September 1, 2026.

If both the U.S. and Romanian social security systems cover a worker’s employment or self-employment, the Agreement provides that beginning September 1,2026, only one country’s system covers the worker’s employment or self-employment. The Agreement does not affect a worker’s coverage prior to September 1,2026. If a worker had dually covered earnings before September 1, 2026, those earlier earnings were and would continue to be subject to social security contributions in both countries.
