Have you decided to apply for dual citizenship, but faced with the task of finding out whether it is allowed in the country of your original and future citizenship? We have published detailed information on how two hundred countries and territories treat dual citizenship in accordance with their laws. You will also learn the identification document of which country with dual citizenship should be used while travelling and where it is possible to obtain dual citizenship in 3-4 months through investment in luxury real estate.
Dual citizenship means that a person has the legal status of a citizen of two states at the same time in accordance with the laws of these countries.
Over the past 20–30 years, there has been a global change in views on dual citizenship from a complete ban to its permission. Currently, 135 countries recognise dual citizenship with all or only a limited number of countries for persons who have acquired citizenship by birth or descent. 5 states do not legally prohibit obtaining citizenship of another country, but at the same time they consider a person as a citizen only of their own country. The legislation of some countries restricts several rights to persons with dual citizenship: for example, it prohibits serving in its armed forces or holding certain government and executive positions.
In 60 states, dual citizenship is prohibited by law, and can also lead to criminal liability or automatic loss of citizenship. Some states make exceptions in certain cases (for example, automatic acquisition by birth) or leave dual citizenship until adulthood, when a person is required to make a choice by renouncing one of the citizenships.
Most countries allow you to renounce your citizenship voluntarily, in other states this possibility is completely absent.

Please note that the lists above are based on open-source research and are for informational purposes only. States often change the rules on dual citizenship by amending the legislative framework. Check the website of the government or embassy of the respective country to find out if dual citizenship is currently allowed or if there is a ban on obtaining the citizenship of another state.
Having received citizenship, a person has the right to apply for a passport – a state document proving the identity and citizenship of the owner when crossing the borders of the state and staying abroad.
Travellers with dual citizenship usually take both passports with them and use the one that makes it easier to visit a particular country.
In most countries, at the border control when entering and leaving the state, it is required to present the same passport for affixing the appropriate marks or scanning the document. This allows the state to find out whether the foreign guest has overstayed his stay in the country.
When visiting a country where you have citizenship, as a rule, you are required to enter and exit only on the passport of that country. Many states, in case of non-compliance with this requirement, apply one or another punishment: from a fine to criminal liability.
Each country sets its own methods and conditions for obtaining citizenship. Individuals may acquire dual citizenship automatically (for example, by birthplace or by right of blood) or upon approval of an application for citizenship of another country (for example, through registration and naturalisation).
