For English-speakers, Romanian is easier to learn than German. And you’ll be speaking Swahili sooner than Polish.
How is that? Because the Foreign Service Institute says so. Located in Arlington, Virginia, the FSI is the U.S. government’s main provider of foreign affairs training, including language courses.
As the chief learning organization for the State Department, the FSI is where diplomats go to study the languages they will need on foreign postings. The Institute has a very practical approach to languages, dividing them into four categories, depending solely on how long it takes to learn them.
