FAQs about dual citizenship
What are the disadvantages of having dual citizenship?
Dual citizenship has potential drawbacks depending on the country's laws, such as citizen obligations, increased bureaucracy, cumbersome passport renewals, military service, double taxation, and being bound by the laws of both nations.
How does dual citizenship affect taxes?
Having dual citizenship can impact your tax obligations, as you may be subject to taxation in both countries. If you're a citizen of a country with citizenship-based taxation (ie. US citizens), you will pay income tax regardless of the country where you are a tax or permanent resident.
How to renounce dual citizenship?
To renounce dual citizenship, you have to give up one (or more) of your passports. The citizenship renunciation process is different in different countries.
Which passport should dual citizens use?
When traveling to a foreign country, you can use whatever foreign passport you'd like to enter – preferrably one with visa-free access.
However, when you are entering one of your home countries you have to use the domestic passport or alternative form of national ID, even if you hold any other foreign citizenships.
How do I pass on dual citizenship to my children?
If you hold citizenship in a country that allows citizenship by descent, your children can automatically qualify for that citizenship as well.
If your child is born in a country that grants birthright citizenship (jus soli), they will automatically gain citizenship of that country, regardless of your own citizenship status.
Lastly, registering your child's birth with the appropriate foreign authorities can also help establish their dual citizenship status.
Do any countries allow triple citizenship?
Yes, several countries allow their citizens to hold triple citizenship or more. These are generally countries whose nationality laws allow dual citizenship without restrictions.
