Ruling on obtaining nationality of a kaafir state

We put this question to Shaykh ‘Abd-Allaah ibn Jibreen, may Allaah preserve him, who replied as follows:

If a person is compelled to seek the nationality of a kaafir state because he has been forced to leave his own country and he can find no (Muslim) country to give him refuge, then this is permissible, on the condition that he is able to practise his religion openly. But with regard to obtaining kaafir nationality for purely worldly purposes, I do not think that this is permissible.
