Today, the White House announced that the United States has signed a Social Security Totalization agreement with Brazil.  According to a fact sheet issued by the White House, the agreement “will eliminate dual Social Security contributions, which occur when a worker from one county works in another country[,]” and “close the gaps in benefit protections for workers who divide their careers between the United States and Brazil.”  The White House estimates that this agreement will save U.S. and Brazilian companies more than $900 million over the first six years.
