I run a website about German bureaucracy. It's how I pay the bills. There is a serious lack of quality resources for the technical parts of immigration. It's incredibly valuable.
The biggest issues people face with immigration - temporary or not - are always the same: housing, joining the various bureaucratic systems and making friends.
If you're a nomad, loneliness is a far more serious issue. While people grow their roots deeper and deeper, you transplant every few months. Some people have no place they call home, and no one to call for help. Locals are not always keen to befriend someone who is right about to leave. Some will resent people who "pass through" their community instead of participating in it.
I could be a digital nomad, but I chose to grow my roots here. I take longer trips, but there is always a place I call home where I am emotionally invested.
