How does an dual citizenship work?

Question

In terms of applying in your own country etc..Do we apply at the same time for both?

Answer 1

The rules for citizenship vary from country to country. You didn't mention the country or countries involved. If you are a minor, you can apply for citizenship in another country upon reaching adulthood.

If you were born in the USA, then you are automatically an American citizen by birth. However, if one or more parent was a citizen of another country, you may qualify for citizenship also in that nation. In practice, many countries permit dual citizenship. If you are applying for citizenship based on the citizenship of your parents or parent, it is a lot easier than for other forms. In some countries, you can ask for citizenship if one or more of your grandparents came from the country.

" Dual citizenship occurs because citizenship can be obtained in more than one way: through country of birth, naturalization, parents, grandparents or, in rare cases, marriage.

"Citizenship is a complex matter because of the great variety of citizenship laws throughout the world. Some countries allow dual citizenship while others take away the citizenship of a person who acquires another citizenship. Some do not recognize a person’s new citizenship. The laws that apply to your case are generally the ones in force at the time of the event that affects your citizenship (your birth or marriage, or your parents’ birth or marriage, for instance). This is why determining your present citizenship status can be a difficult and lengthy process."


There are problems and pitfalls in dual citizenship. Here is one paragraph from :"wikipedia: multiple citizenship" :

"Although being a citizen of more than one country can be helpful as it affords two or more passports, it is prudent to realise that each citizenship carries responsibilities. This may bring about problems in conscription, as well as allegiance to more than one state. A dual citizen is subject to travel restrictions, embargoes and sets of laws issued by multiple governments governing one's behaviour domestically and while travelling abroad. Also, as a drawback peculiar to a few countries such as the U.S., citizens are obligated to pay taxes in both the country of origin and the actual country of residence. However, many countries and territories have contracted treaties or agreements of avoiding double taxation."

In any event, you will have to write to the Embassy of the country you are interested in; they will be able to give you the legal paperwork and current laws and regulations regarding citizenship applications.
