> "A few months ago, a friend sent me a link to a university doing clinical trials using stem cells to repair the heart. It seemed really promising. Unfortunately, they are in Germany, and they only accept German residents. So that wasn’t an option."

It's not that tough to gain German residency. There's even a "Freelancer Visa" that gives you a residence permit. If you pay an immigration consultant a few thousand bucks, and don't have a criminal history, it can be done rather quickly.
