I'm sure this has been discussed before but: I'm in the midst of planning a trip to Europe. I'm an Australian citizen, born and bred, and I'm only 22. I'm organising a working holiday scheme (WHS) visa for the Netherlands as I have a friend there who can line me up with work if I want it. The terms of the visa let me travel around as much as I like in the Schengen area for up to 1 year, but only work in the Netherlands, as it is organised through the Dutch consulate specifically. Just so we're clear, this is different to a Schengen Travel Visa, which allows free movement for 90 days in a six month period in the Schengen area. I want to stay in Europe for more than 1 year though.
So my question is: Can I organise another year-long working holiday visa in another country within that Schengen area (I'm thinking Germany) towards the end of my Netherlands visa to allow me to travel around for another year? If not, can I organise a visa for the UK easily at that time, and does the UK visa allow travel into the schengen area so I could go back and catch anything I missed in the first year?
Failing all that, is there any other way I can stay in Europe for more than 1 year without having to commit to studying or working the whole time, as I spent the last three years in Australia working 7 days a week to save enough money that I can blow it all just travelling around and seeing as much of Europe's beauty as possible?
