Pros

• ANOTHER COUNTRY. Hi.
• Visiting new places, experiencing life elsewhere.
• New food!
• Different language, immersion is 100% the best way to learn

Cons

• No friends or family, could be very isolated.
• Different language, meaning no more conversations in English. (Or at least, a significantly fewer amount.)
  • Also, less easy access to books. No libraries or bookstores (with things I can read, anyway).
• Getting a job abroad is difficult.
