What is the ruling on acquiring the nationality of a disbeliever’s country?

Question:
He says: Honorable Shaykh, may Allah grant you success. He says: This questioner is from Europe. He says: He lives with his family in Britain, and all of his family members have British nationality, but this brother has Albanian nationality. His question is: Is it permissible for me to take British nationality so that I do not face harassment?

Answer:
It is not permissible for a Muslim to acquire the nationality of the disbelievers. A decision was issued regarding this by the Fiqh Council of the Muslim World League years ago, stating that it is not permissible for a Muslim to acquire the nationality of the disbelievers, because their system applies to him and he becomes subject to their system, and this is not appropriate. However, he may take a residence permit; there is nothing wrong with taking a residence permit, provided he does not take their nationality. Yes.
