Frequently asked questions.

Citizenship is the legal bond between a person and a state. It determines which country you belong to, which passport you can carry, and which government owes you protection. A citizen has rights the state cannot easily take away: the right to live and work in the country, to vote, to hold a passport, and to receive consular help abroad. In return, citizens take on obligations. Depending on the country, these can include paying taxes, serving on juries, or completing military service.

Naturalization is the legal process by which a non-citizen becomes a citizen after meeting specific statutory requirements—residency periods, language proficiency, civics knowledge, and character assessment. It's the formal endpoint of an immigration journey: the moment a foreign national becomes a full citizen with all associated rights and responsibilities.

Nationality and citizenship aren’t the same thing: nationality points to where you “belong” in terms of peoplehood (roots, culture, and heritage) while citizenship is the official, government-recognized legal membership in a state.

Yes, in countries that allow dual citizenship without restrictions. Some countries, like the Netherlands or Singapore, don't allow their citizens to have any other citizenship. Others, like El Salvador or the USA, allow dual citizenship without restrictions, meaning you can acquire a second or third citizenship while keeping any other citizenships you already hold.

Citizenship is your legal status in a country—your formal membership. It usually comes with rights (like voting and access to certain public services) and responsibilities (such as obeying laws and, in some places, paying taxes or fulfilling civic duties).

A passport, by contrast, is the travel document a country issues to its citizens. It proves identity and nationality when crossing borders and requesting entry abroad.

Citizenship is generally meant to last for life. It can be gained by birth, descent, or naturalization, and it doesn’t expire like a document.

A passport is time-limited. It can be lost or replaced, may have different validity periods for adults and children, and must be renewed to keep traveling easily.

The main benefit is having a Plan B, and not depending on a single country. Having a second passport removes the single point of failure of having just one citizenship. Besides that, there are many benefits such as more optionality, privacy, asset protection, global mobility, access to business opportunities, and overall freedom not just for you but also for your future generations who will inherit a second passport from you.

There are five ways to get a second passport: by naturalization, marriage, descent, investment, or exception.

Citizenship by investment programs allow you to get full citizenship in exchange for predetermined economic contributions. These programs are backed by citizenship laws, and contrary to citizenship by merit programs, have clear due diligence and economic requirements that need to be met in order to get citizenship.

The main benefit of citizenship by investment is the ability to acquire an alternative citizenship without residency or physical presence requirements, language or history tests, or any other complex or lengthy procedures.

Citizenship by investment programs offer the most streamlined path to citizenship. It’s precisely this flexibility and efficiency that high-net-worth individuals and families seek in exchange for their economic contributions to the host country.

Citizenship by descent programs are legal pathways that allow you to claim citizenship and obtain a passport based on your ancestry. Many countries allow the world have citizenship laws that allow foreigners to claim citizenship by descent given applicable conditions and requirements are met.

The documents required to claim citizenship by descent vary by country. Typically, a valid passport and clean criminal record are required, as well as documents proving your ancestry. You can check the exact documents required for each program at CitizenX.
