Question

Answer 1

If you have a British passport then you are free to move to any of the mentioned countries to live & work so that is not a problem.  How this affects your greencard status or not, is not an answer I can help with sorry

However, at least for the Netherlands you should be 18 to work as an Au pair.  You can see the details (in case you didn't have a British passport) here on the official Dutch Immigration Department site, and it states the age of 18 is required http://www.ind.nl/EN/verblijfwijzer/verb...
