At the very least, a couple of U.S. companies with remote positions that claimed to be U.S. only (or "work authorization required?"), reached out to me.
But I think some companies select U.S. only because Americans tend forget about other countries where people may be in the same time zone.
It's possible German companies are reluctant to engage with a Swiss person because German salaries are lower than what I understand Swiss salaries to be (German CoL is also much lower though)
