I relocated permanently back in 2021, in fact, soon after finishing up undergrad at Northwestern. I'm a dual US/EU citizen and I moved to be with my Finnish wife. I'm here now!
I don't have a blog post to share. My experience here has been largely positive, modulo the obvious financial caveat: My take home salary really is about ~30% of what it would be had I stayed back in the United States and followed a similar career trajectory. In the long run I think this is an eminently fixable problem, however :)
