Hi Fester,
For a couple of months, its not worth thinking about the states, the work permit process was a real ballache and a money drainer, also for that amount of time you will struggle to get a good salary, that was my experience any way.
Maybe try canada, they have a more relaxed aproach and plenty job offers came in when i looked at it.
Here in Norway the cash is pretty good but some find it hard to adapt to the pace here, for me its all good.
I was in NZ myself for a few years, some time in Auckland but mainly in christchurch. cold winter nights indeed!
happy job hunting
Andy
