For me, personally: I'm fairly introverted myself and generally had only a few friends near me before I moved, so it suits me well. Also: I've been here a decade or so and I moved for marriage - I've always had at least one friend here. I've worked a little bit. And then I got into board games (both immigrants and local folks), so I meet some folks that way. The person that organizes the games, though? They struggled a bit for a while.
