There are a good number of free language classes in Pittsburgh at the Carnegie Libraries: Japanese, Chinese, Korean, German, French, Spanish, English as a Second Language, among others (search events on the CLP webpage for details). If you're looking for one-on-one exchanges, or just want to chat with someone from a different country, many local universities and language institutes run language exchange and conversation partner programs to help their international students share quality time with native English speakers, time that can be surprisingly hard to come by. A new semester means renewed need for conversation partners, and if you're in Pittsburgh you can contact the University of Pittsburgh's English Language Institute or Duquesne University's ESL program.
Schools in other areas have these outreach programs, too, so Google around. Indiana University of Pennsylvania, Penn State, and the University of Pennsylvania come to mind. It's a great way to help someone new to your city and to make a meaningful experience for both of you.
