I was kept on a very tight schedule growing up, so I can understand a little how that feels. I was happy for the free time I was allowed, but my father was very strict about the hobbies I was allowed to pursue. I'm lucky he found things like playing instruments to be cultured!
I don't have a degree either, if that helps. I've wondered what I'd pursue if I decided to, but I have no idea if that day will come. It does seem a little pointless at the moment. And when would I find the time?
You could do that, the green card thing! If you need a reference or something like that, I'd be happy to help! If you want to perform here you'll definitely need to go through all the red tape eventually.
