Dual Citizenship Around the World
Can you hold two nationalities? It depends on both countries. This guide shows, for each country, whether its citizens may hold another nationality, whether a foreigner must give up the old one to naturalise, and how many years of residence the ordinary route takes.
Part of the comparative law toolkit. 61 countries so far; the others are shown pale. These are the general rules for the ordinary routes; birth, descent, marriage and refugee routes have their own rules.

Read this first
These are the general rules for the ordinary routes, not your case. Nationality law has many special routes (birth, descent, marriage, refugees, investment) and exceptions, and details change, so check the current law and ask the country's nationality authority. This is general information, not legal advice.
Two countries, two rulebooks
Two countries, two sets of rules
Each country decides for itself who its citizens are. One country can allow dual nationality while the other takes its own nationality away, so check the rule of BOTH countries before you naturalise or apply for a second passport.
A country may treat you only as its own citizen
Many countries do not recognise your other nationality inside their borders. You may have to enter and leave with that country's passport, and its authorities may refuse consular help from your other country.
Duties can follow you
Military service, tax filings and voting duties can apply to each nationality. The United States, for example, taxes its citizens on worldwide income wherever they live.
Renouncing is permanent, and not always accepted
A formal renunciation may be hard to reverse. Some countries do not allow their citizens to renounce, so the paperwork may achieve nothing.
Ask the authority, not only a website
Nationality law has many exceptions for birth, descent and marriage, and details change. Confirm with the country's nationality authority or a lawyer there before you act.
May citizens hold two?
Whether the country lets its own citizens also hold the nationality of another country. Some countries allow it freely, some only in listed cases (for example by birth to parents of two nationalities, or with certain countries), and some end the nationality of a citizen who voluntarily takes another.
Must new citizens give up the old one?
Whether a foreigner who becomes a citizen by naturalisation must give up their previous nationality. Even where the answer is yes, the other country may not accept the renunciation, and then you may end up with both in practice.
Years to naturalise
The usual number of years of legal residence the ordinary route to naturalisation needs. Shorter periods often apply to spouses of citizens, refugees, people of the country's descent or graduates, and some countries need permanent residence first, which can add years. Language, integration and income tests apply almost everywhere.
