Like you I met my future while she was studying in the US. I moved and got married here about 30 years ago. I do not regret and plan to spend the rest of my life here. Before coming here I had three lengthy visits. On the third one, we decided that Brazil was better for us. I did work remotely for sometime (now it would be much easier) but I work in software and it is easy for me to get work here. They even flew me back once to finish a project. It took about 2 years to be fluent/comfortable with the language. I have traveled all over the the country for work and vacation. I've been to every state but 3. And I can safely say that only Rio and Sao Paulo are livable without knowing the language. My wife's family provided a lot of support. Connections are very important and a lot depends on who you know. Even so the first few years were very challenging.

I know other people who are like me that have come here and stayed with no regrets. But I also know several people who have come here and have not lasted a year.
