Citizenship is considered a human right and usually a permanent status. As part of international law, everyone has the right to a nationality and no one should be deprived of one. While citizenship does not expire, it can be revoked in a number of different scenarios. This can depend on the country’s laws but can include committing an act of terrorism or treason. On the other hand, your passport may expire – usually after 10 years and will need to be renewed with the relevant authorities.
