It’s common within intelligence agencies to recruit multi-lingual individuals and to teach current operatives foreign languages. This enables them to spy, make deals, research, produce propaganda, and conduct in other nefarious activities successfully. These are the types of assets the C_A requires and trains at their covert facility known as “The Farm” at Camp Peary, located in Virginia.
According to Wikipedia:
…Camp Peary hosts a covert CIA training facility known as “The Farm”, which is used to train officers of the CIA’s Directorate of Operations, as well as those of the DIA’s Defense Clandestine Service,[1] among other intelligence entities. Camp Peary has a sister facility, “The Point”, located in Hertford, North Carolina.
