Unfortunately, it's the Swiss who have the policy.
Switzerland has Europe's toughest naturalisation laws. Foreigners must live for 12 years in a Swiss community before they can apply, and being born in Switzerland brings no right to citizenship.
Under the current system, foreigners apply through their local town or village.
They appear before a citizenship committee and answer questions about their desire to be Swiss. After that, they must often be approved by the entire voting community, in a secret ballot, or a show of hands. This practice, the report says, is particularly likely to be distorted by racial discrimination.
