The agreements also have a positive effect on the profitability and competitive position of companies operating abroad by reducing their business costs abroad. Companies with staff stationed abroad are encouraged to use these agreements to reduce their tax burden. Under certain conditions, a worker may be exempt from coverage in a contracting country, even if he or she has not been transferred directly from the United States. For example, if a U.S. company sends an employee to its New York office to work for 4 years in its Hong Kong office, and then re-opens the employee for an additional 4 years in its London office, the employee may be a member of Social Security under the U.S.U.K. agreement. The rule for the self-employed applies in cases such as this, provided the worker has been seconded from the United States and is under U.S. Social Security for the entire period prior to the transfer to the contracting country. Spain and Portugal are covered by both a bilateral agreement and the Treaty of the Ibero-American Social Security Organization. You can also write to this address if you want to propose negotiating new agreements with certain countries. In developing its negotiating plans, the SSA attaches considerable importance to the interests of workers and employers who will be affected by potential agreements. Despite the fact that the agreements aim to allocate social security to the country where the worker is most attached, unusual situations occasionally arise, where strict enforcement of the rules of agreement would result in unusual or unjustified results. For this reason, each agreement contains a provision allowing the authorities of both countries to grant exemptions from the normal rules if both parties agree.
An exception could be granted, for example, if the foreign award of a U.S. citizen was unexpectedly extended by a few months beyond the 5-year limit under the self-employed rule. In this case, the worker could benefit from ongoing U.S. coverage for the additional period. The single-family home rule in U.S. agreements generally applies to workers whose interventions in the host country are expected to last 5 years or less. The 5-year limit for leave for exempt workers is much longer than the limit normally set by agreements in other countries. Applications should include the name and address of the employer in the United States and the other country, the full name, place and date of birth of the worker, nationality, U.S.
and foreign Social Security numbers, location and date of employment, and the start and end date of the assignment abroad. (If the employee works for a foreign subsidiary of the U.S. company, the application should also indicate whether U.S. Social Security Insurance has been agreed upon for employees of the related company pursuant to Section 3121 (l) of the internal income code.) Self-employed workers should indicate their country of residence and the nature of their self-employment.
