19. Prepare to stay in touch with your friends and family.
Stay in touch with your family and friends in the U.S. while you're abroad by using video chat programs, such as Google Hangout or Skype. Your cell phone might work in another country, but if not, you may be able to get a cell phone locally. Otherwise, you can buy an international calling card to use for phoning home. Being able to talk to your family and friends can go a long way in staving off homesickness.
