You no longer have to give up citizenship to be a German citizen, and the US doesn’t require that either. A new law passed this year and comes into effect sometime around April I believe (still new to the exact legislation process in this country).

But yes, I would not encourage anyone to move to the US at this time. They are the largest proponent of late stage capitalism and those policies bring instability to the worker classes which begets authoritarianism. That’s rarely a good thing for anyone.
