Write senators and congresspersons. Volunteer in after-school programs (either teaching language, tutoring, or helping ESL students). Join a local language club. Correspond by email with someone from a different country in your professional field. Be a volunteer host for international visitors (being a host could be as simple as offering dinner hospitality to an international visitor). Get involved in high school student international exchange programs, helping host parents and promoting exchanges.
