UK and Germany would also be good options. I know the UK has a points based system so if you are highly educated with a good salary in the US you will most likely meet the highly skilled point quota and receive a work permit.

In the UK if you have a Tier 2 visa then you apply for "Indefinite leave to remain" after 5 years of residency. The only restrictions are that you cannot spend more than 180 days outside the UK in any 12 months and your employer (sponsor) still needs you for your job.
