The concept of citizenship has been around for centuries, yet the term has evolved over time to redefine what it means to be a citizen of a country or even of the world. While, in its basic definition, citizenship remains the legal status held by a citizen within a state, that state no longer has to be the country of a person’s birth.
Some of the most common types of citizenships are
jus sanguinis, a Latin term also known as “right of blood” or ancestral citizenship,
jus soli, which means citizenship achieved based on where an individual is born,
jus matrimonii, known as citizenship through marriage, and
naturalisation, which refers to citizenship granted after an individual has spent sufficient time in a country.
Family Citizenship: Jus Sanguinis
One of the most common paths to citizenship is
jus sanguinis, a Latin phrase translated into English as “right of blood”. This describes an individual whose parent, grandparent, or other family member is already a citizen of a different specific state from the country in which the individual was born. Countries that offer this citizenship outright include France, Greece, Italy, Japan, Romania, Thailand, and Turkey.
Citizenship by Birth: Jus Soli
Jus soli, another Latin term meaning “right of soil”, generally refers to the rule granting citizenship to an individual who is born in a country. However, this does not apply in every country, and certain legal regulations may restrict individuals in some nations under what is known as
lex soli law. Some of these countries include Australia, Egypt, New Zealand, and South Africa. In many jurisdictions such as Canada, Israel, or Greece,
jus sanguinis and
jus soli are combined into one model. This offers individual citizenship to their birth country, as well as that of one or both parents.
Citizenship by Marriage: Jus Matrimonii
Known legally as
jus matrimonii, becoming a naturalised citizen by marrying an individual with citizenship has become common practice since it was introduced in the wake of the Second World War.
Rules differ across the world with regards to how long a couple will need to be married before citizenship will be granted, and some nations also extend this right to couples in civil partnerships.
Naturalisation
Naturalisation usually applies to those who have entered the country through legal means, such as political asylum or having lawfully lived there for a mandated period.
For those becoming new citizens, it is customary to take a test that demonstrates an understanding of the nation’s laws, culture, tradition, and language. In countries that do not offer dual citizenship, new citizens are also required to renounce their old citizenship.
Economic Citizenship or Citizenship by Investment
For those unable to acquire citizenship in more traditional ways, economic citizenship can be a viable path. Citizenship by Investment (CBI) programmes give investors a means of gaining citizenship through a meaningful monetary contribution to a country’s economy.
There are currently over a dozen active CBI programmes in existence, the first being for
St Kitts and Nevis, which dates back to 1984.
