Yes, I would qualify straight away for citizenship as I speak the language and will have an almost fully-paid pension here by the time I retire. But although I love living here (obviously) I would have to give up my British citizenship, which would potentially cause problems with family, partner, etc. Problematic either way... (which is why it is infuriating we didn't get to vote and Commonwealth residents in UK, for example, did).
Added: Before Austria was in the EU, you could live and work here but you had to apply for permission at the local government level and were granted a limited 'permission to stay' if successful (bit like Swiss but not as hard).
I understand your plight mate. You've been put in a very undesirable situation, not of your own choosing. If you ask me; the modalities of that referendum were a mess, no nuance once so ever. A mockery. Even so the cards have been dealt and it has to be respected (one way or another).
I didn't know that Austria doesn't allow double citizenship. Here in Belgium it's commonplace. I suppose you could put your trust in your current government that they work out some kind of reciprocal arrangement. How's your situation looking at the moment; how does retirement work for non-EU people who want to retire in Austria ?
