Alper Yilmaz has no doubt where his home is. "My homeland is Austria, Vienna," he says.
But with a far-right party sharing power and anti-immigration sentiment generally on the rise in Austria, Yilmaz -- along with potentially thousands of other Austrians with Turkish roots -- is worried he could be stripped of his citizenship.
Except in very special cases, Austria does not allow its citizens to hold dual nationality.
But the far-right and anti-Islam Freedom Party (FPOe) -- junior partner in a ruling coalition with the centre-right Austrian People's Party (OeVP) -- last year claimed to have received a list of Turkish voters which it said could contain tens of thousands of illegal dual nationals.
