Can citizenship expire?

Whether or not you have duel citizenship really depends on how things are interpreted. You have citizenship in the country in which you were born. You may have citizenship in the country where your grandparents raised you IF they or someone else applied for citizenship for you. If they did do that then you hold two citizenship....and no, they don't expire.

At the same time however you must remember that not all countries allow for duel citizenship. Take India for example. My daughter was born there and therefore had citizenship by birth. She was adopted by us as an infant and we moved her out of India once we had the paperwork done for her to immigrate to Canada and live with us. She then would conceivably hold Indian AND Canadian citizenship....right? Wrong. India does not allow it's citizens to hold duel citizenship therefore she legally lost her claim to Indian citizenship and is not just Canadian.

Israel is somewhat similar. You can hold, for example, US citizenship and Israeli citizenship if you wish however Israel only recognizes it's own. If you hold both and go to Israel on vacation, lets say when you are 20, you will most likely find yourself being forced into military service over there and you won't be able to weasel out of it saying that you are American because they only recognize your Israeli citizenship.

Either you have citizenship or you don't, you can't renew it, it doesn't come with an expiry date but there are other ways to lose it

The citizenship of your home country may have allowed you to live with your grandparents, you may also have citizenship of your grandparents home country through your mother - for instance if you were born in the UK to an Irish mother, you would automatically have been an Irish citizen at birth through her but you would also be a British citizen because of a tweak in British law that I won't go into, if you then moved to Ireland with your grandparents your British citizenship would have allowed you to legally live there with them or any other EU member state

If you have no claim to citizenship in a country through birth then you don't simply gain citizenship by living there, there is a legal procedure to go through to become a naturalised citizen & it occasionally happens (it's not necessarily the case) that a child is left with relatives & may have a questionable legal status that is never explored you might want to establish with your mother what your exact status was

relies upon on your definition of "expires"! In some international places you're allowed to have twin citizenship as much as a undeniable age after which you would be able to desire to chosen one or the different. There are different international places the place in case you have twin citizenship and you do no longer do particular issues (varies by way of u . s .)to maintain your citizenship is not any longer valid.

Depends on the country. In some, after your 21st birthday you have to reconfirm that dual citizenship.
