Germany also has single-payer socialized healthcare IIRC. The US has Medicare/Medicaid/Obamacare which isn't so great, and often doesn't include dental or vision care. For a long-term living situation, that's probably more important.
Also, the US immigration and refugee systems are arbitrary, byzantine, gotcha minefields that can suck would-be visitors into indeterminate imprisonment or expelled for minor paperwork errors or unintentionally breaking one of a billion unclear rules.
if you are interested, let me know.
