Dual citizenship is defined as being a citizen of two countries simultaneously. Dual citizens have two passports (one from each country) and enjoy the rights, privileges, and responsibilities of each country. A person can become a dual citizen in different ways.
U.S. nationals, including dual nationals, must use a U.S. passport to enter and leave the United States. Dual nationals may also be required by the foreign country to use its passport to enter and leave that country.
Dual nationality (also known as dual citizenship), is where an individual enjoys two (or more) nationalities. An individual with dual nationality is born with citizenship in one country, and may then acquire another nationality by choice.
Defining “Entering” and “Exiting” a Country
Entering a country is when you land and you go through passport control. You will enter your destination country, but you will also re-enter the country that you are returning to. And this may cause you to use two different passports on the same journey.
Two Passports
As a dual citizen, you are allowed to carry passports from both countries. For example, if you are a U.S. citizen and also a citizen of New Zealand, you can travel more easily between these two countries.
The United States allows naturalized (and other) citizens to become dual citizens with their home countries (though it's not possible for everyone, depending on the laws within said home countries). And if you're a dual citizen, you may not only keep your old passport, but travel with it, if you wish.
There are no real restrictions or definitive rules on which passport you use to book a flight, or any other form of international travel whether via ferry or train. For example, the British passport may allow visa-free entry to more countries than your other passport.
Dual citizenship — or dual nationality — means being a citizen of two countries simultaneously and sharing the rights and responsibilities of the citizens in each country.
Dual citizenship (also known as dual nationality) is allowed in the UK. This means you can be a British citizen and also a citizen of other countries. You do not need to apply for dual citizenship. You can apply for foreign citizenship and keep your British citizenship.
We recommend all dual nationals, including EU citizens, travel on their British passport or with evidence or their British citizenship to minimise any potential delay at the border or when commencing their journey.
Disadvantages of Dual Citizenship
It may be that the taxes are doubled if you have dual citizenship. U.S. citizens, even if they are outside the country, must continue to pay taxes from their country of origin and the country in which they are located.
You are not required to present documents that you used to travel to other countries with. The main thing to remember is that at the entrance and exit from the same country, you must present the same document. But you can buy plane tickets with any passport.
You can have a two UK passports at the same time.
Therefore, if there are any modifications in the laws, the citizens get enough time to take the required action to remain the citizens of the country. Hence, dual citizenship never expires.
Is it illegal to have three passports? If your nation does not allow dual citizenship or more then yes it is illegal, unless you renounce that citizenship of course. If your nation allows dual citizenship or more then it is fully allowed and legal to have three passports.
Voting and citizenship
Your UK citizenship will not be affected if you move or retire abroad.
Contents. The coalition government committed in 2010 to reintroducing exit checks. From 8 April 2015, we will collect information on passengers leaving the UK as we do for those entering. Exit checks will provide us with vital information that confirms a person's exit from the UK.
There has been a surge of applications to EU countries by UK citizens who want to retain their EU citizenship. Although the UK does allow dual citizenship, not all countries allow it. Certain EU countries do recognise dual citizenship, such as Ireland, Italy, Belgium, France and Portugal.
The old passport may be sent separately from your new passport. We recommend keeping your old passport in a safe place as it is considered proof of your U.S. citizenship. If your old passport is linked to a valid visa, you can still use the valid visa. You must travel with both your new and old passport in this case.
A passport is evidence of citizenship and also serves as a travel document if you need to travel. For information about applying for a U.S. passport, see the U.S. Department of State Web site at www.state.gov.
Your passport will generally be processed in 4-6 weeks. However, if you need it sooner, then you can pay $60 for expedited processing. You will receive your expedited passport in 2-3 weeks typically. If you choose expedited processing at selected government agencies, then you can get the passport in five business days.
