What Is Dual Citizenship and How Does It Work?

The dual citizenship meaning is very simple. It is a status by law in which a person is considered to be a citizen of two nations at the same time. That is, they are each other's citizen and can be granted certain rights, protections and responsibilities under their own laws. 

If you're wondering what dual citizenship is, think of it as maintaining a legal connection with two nations simultaneously. This may occur in various ways. There are many instances in which individuals obtain dual citizenship as a result of birth, ancestry, marriage or naturalisation.

Different countries have different laws that dictate their citizenship policy.

• Many countries allow citizenship through birth, and this is probably the easiest way to get citizenship in a country.

• Other than this, if any or both the parents have dual citizenship, the child can become a citizen of his or her parent’s countries.

• You can also obtain citizenship of a country by marrying someone who is a citizen of that country. Some countries do not offer citizenship straightaway, but you can apply after spending a certain amount of time in that country.

• Some countries also offer citizenship based on ancestry. If you have lineage from that country, you can apply for its citizenship.

• Some countries also offer citizenship to investors. One has to invest in their economy through setting up businesses or investing substantially in existing businesses. This is also known as citizenship through investment.

It is important to know that not all countries allow dual citizenship. For example, if you are an Indian citizen who obtains citizenship in the United Kingdom, you have to surrender your Indian citizenship and passport.

The constitution of India does not allow its nationals to have dual citizenship. You may get nationality from another country, but according to the Passports Act of 1967, Indian residents having acquired nationality from other countries must surrender their Indian passports to the nearest embassy.

In simple words, maintaining dual citizenship in India is not allowed. However, a Person of Indian Origin (PIO) who migrated to another nation and obtained citizenship can apply for Overseas Citizens of India (OCI) status. However, the PIO must not have citizenship in Pakistan or Bangladesh.

There are certain benefits of conceding the nationality of a developed first-world nation. Citizens of such a country get many social benefits that Indians do not get in India. However, if you reside in India and want to become a citizen of another country, you must surrender your Indian citizenship.

India is not a double citizenship country; its constitution does not allow its citizens to take up other countries' nationality.

However, a PIO can apply for registration as an Overseas Citizen of India (OCI).

Indian law does not allow "dual citizenship," but eligible persons may apply for Overseas Citizen of India (OCI) status. The OCI scheme, in practice, has been introduced to help people of Indian origin keep a long term affiliation with India even if they get foreign citizenship. It is not a citizenship but it makes travelling, living and some administrative procedures much easier.

Individuals of Indian origin

This is a major category of OCI applicants. The following are conditions for a person to be eligible for OCI: 

• Have been a citizen of the Republic of India born on or after 26th January 1950. 

• Went to a region that was an integral part of India after Independence. 

• Were eligible to become an Indian citizen when the Constitution came into effect. 

• Be a child, grandchild or great-grandchild of an Indian citizen.

Foreign spouses of Indian citizens

OCI eligibility is not limited to people of Indian origin. In certain cases, foreign spouses may also qualify.

This generally includes:

• Foreign nationals married to Indian citizens.

• Foreign nationals married to existing OCI cardholders.

It is important to note that the marriage should be registered and meet the Government of India requirements at the time of application. These requirements may be subject to change over time so it is best to check the latest requirements for each application.

Eligibility for children

Children can also qualify for OCI registration under specific circumstances. For example:

• At least one parent is an Indian citizen.

• One or both parents hold OCI status.

• The child meets the eligibility requirements through family lineage.

In many cases, these provisions help families preserve their ties with India across multiple generations, particularly when family members live and work in different countries.

Not everyone can apply for OCI status. Certain restrictions apply under Indian law.

Generally, OCI registration is not available to:

• Individuals who have held citizenship of countries specifically restricted by the Government of India.

• Applicants who do not meet the prescribed eligibility requirements.

In essence, it is based on both family history and government regulations at the time. Citizenship and immigration requirements may change over time, so it's always best to review the official requirements before beginning the application process.

To collect the OCI card, which sort of doubles as dual citizenship in India, one must submit the following documents: 

• A duly filled OCI application form

• Cancelled Indian passport

• The passport of the country of residence

• PIO card

• A copy of the receipt of the payment of fees

Many countries allow dual citizenship now, meaning people can have citizenship in two countries. Over the last few decades, with the rise of international migration, numerous countries have changed their citizenship regulations to better accommodate those who reside, work, study or have family connections in other nations.

That's not always the case, though. There are different ways of doing things across each country and rights of dual citizenship may vary greatly. Let's take a closer look at how it is handled in different countries.

Countries with flexible dual citizenship policies

Dual citizenship is recognised by some countries in a broad manner and citizenship is generally not lost upon acquisition in most countries.

Examples include:

• Canada

• Australia

• New Zealand

• United Kingdom

• France

• Ireland

• Switzerland

• Belgium

In practice, these countries have developed citizenship frameworks that reflect today's global workforce and increasing international lifestyles.

Countries that commonly permit dual citizenship

Several countries also allow dual citizenship through routes such as naturalisation, marriage, birth, or family ancestry.

These include:

• United States

• Italy

• Portugal

• Greece

• Sweden

• Finland

• Denmark

• Luxembourg

This can be especially beneficial for those who are busy, flexible is the key. This flexibility can be especially helpful for busy people. It could offer greater employment prospects, access to education networks, healthcare benefits and longer-term opportunities for residence in more than one nation.

Countries with certain conditions or exceptions

Not all countries follow an entirely open approach. Some permit dual citizenship but apply specific restrictions depending on how citizenship is acquired.

Examples include:

• Germany

• Netherlands

• South Korea

• Brazil

• Philippines

Worth noting, eligibility requirements in these countries can differ based on factors such as birth, descent, marriage, or naturalisation. As a result, the same rule may not apply to every applicant.
