Second Citizenship for the Family in 2026: How to Include a Spouse, Children, and Parents

In 2026, families are considering second citizenship as a "backup plan": a strategy that lets an investor secure status not just for themselves, but also for their spouse, children, and, under some programs, their parents.

A second passport opens up major opportunities for living, working, educating children, and passing on family assets.

Who counts as a dependent family member (Dependents)?

In 2026, the Main Applicant can include financially dependent family members in a second citizenship application: they can join as Dependents. This usually means a spouse, children, and parents.

1. Spouse. The most common dependent category. When applying, you need to provide a marriage certificate and documents for both spouses. If the couple is in a civil partnership or a same-sex union, eligibility for citizenship isn't always guaranteed (it depends on the program). Simply stating the relationship isn't enough for the application – it must be legally recognized in that jurisdiction.
2. Dependent Children. Minor children are another category included in the application. The rules are simpler for them, and confirming their age is enough (children under 18 are included without proof of financial dependency). For adult children, the application takes into account the absence of their own income, full-time education, living together, and being financially supported by the applicants. There's no age limit for children with disabilities.
3. Dependent Parents. This category isn't included in every family application program, and when applying, age, financial dependency on the investor, and shared residence are taken into account. To confirm dependency, documents (Proof of Dependency) may be required showing the absence of independent income, bank transfers from the investor, proof of shared residence, a document confirming the family relationship, and pension documents.

Investment passports for children and parents (dependents) differ from country to country: in some cases, documented proof of the family relationship is enough, while in others – for adult children and parents – financial dependency must be demonstrated.

It's important to distinguish between residency programs and Citizenship by Investment. For example, in Turkey or the Caribbean, citizenship can be obtained by meeting investment requirements, while in Italy, Spain, or Greece, a Golden Visa is a path to a residence permit and only leads to citizenship once naturalization conditions are met.

Each program has specific terms and requirements relating to financial dependency, children's age, additional fee amounts, and marriage requirements.

Comparing countries by conditions for including family in a second citizenship application

Turkish citizenship for the whole family is one of the easiest ways to obtain a second passport: the investor buys property worth $400,000 or more and goes through a simplified process for a second passport, and family members can be included in the application.

A Caribbean passport for an investor, spouse, and children can be obtained with a smaller investment amount, but

with a longer list of requirements and additional fees for each dependent.

Let's look at popular naturalization destinations and the program conditions that must be met when applying to include a relative.

Can family members be added after obtaining the passport?

Many investors care about whether a family member can be added to a second citizenship application after the passport has already been obtained. Certain mechanisms exist for this.

For a newborn child, a separate process must be followed. Information must be submitted to the relevant authorities after the birth, since the child's details can't simply be added to the passport directly. A birth certificate and other documents must be provided according to the specific country's conditions.

A new spouse, or parents who reach the required age later, are reviewed separately.

In cases where parents weren't intentionally included in the application earlier, their inclusion may follow a different process.

How much does citizenship cost for a family of 4?

For Caribbean programs and Turkey in 2026, obtaining a second passport involves not just the main investment amount, but also a number of related costs in the form of government fees, checks, and additional payments.

The final budget is made up of:

• the contribution or investment amount;
• the application fee;
• the due diligence and processing fee;
• interview fees;
• document and legalization costs;
• agency and lawyer support;
• notary services;
• additional fees for family members.

Let's look at the cost of an application for a classic family model – Main Applicant + spouse + 2 minor children.

Documents and Due Diligence checks for the family

Second passport program options differ in their processing mechanisms. It's important to realistically assess your family's total budget, the composition of your Dependents, and the Due Diligence requirements.

For one family, a program that allows including adult children and parents might be ideal; for another, Turkey through property investment might be the better fit.

For some, a European Golden Visa may work well as a long-term path to residency and naturalization.

When documents are submitted, the relevant authorities review not only the Main Applicant but also the included Dependents.

Basic document checklist:

• passports;
• birth/marriage certificates;
• adoption/guardianship documents;
• education documents;
• bank statements and information on the source of funds;
• proof of residential address;
• criminal record certificates;

• Proof of Dependency for dependent adults.

The origin of investment funds undergoes thorough checks, as does any negative information about relatives. If violations are found for any family member, this can trigger additional requests or negatively affect the application.

For a child over 18, you can provide documents confirming full-time education, the absence of independent income, and information on money transfers from the parents.

Golden Visa: Greece and Italy – rules and conditions in 2026

European programs follow a separate process and approach to obtaining citizenship.

A "Golden Visa" is not second citizenship. By investing in Greece's economy, an investor only obtains grounds for residency – it does not guarantee a second passport.

The applicant's family can also obtain the right to long-term residence, with citizenship potentially obtainable later by meeting the state's naturalization conditions.

In Italy, obtaining a second passport also happens through residency. For family reunification, the law allows including a spouse, financially dependent children, and parents once conditions are met.

Important: in Spain, the Golden Visa program has been discontinued for new investors.

FAQ: second citizenship for the whole family

Can children from a previous marriage be included in the application?

Yes, if the child meets the program's conditions. If there's a second parent, written consent, a court custody ruling, or adoption documents are required. 

Can a child over 18 be included?

Yes, depending on the country and program, if they qualify as a Dependent Child, are financially dependent, and meet the education requirements. 

Is it allowed to include parents?

For programs that include the Dependent Parents category, this is allowed once the relevant conditions are confirmed.

Is it possible to add a newborn child after obtaining citizenship?

Yes. There's a special procedure for this, which involves registering the child, preparing documents, and paying fees.

Can siblings be included?

Siblings don't fall under the standard Dependents category. If needed, you'll need to choose a country where these relatives can be added under a separate program or with additional conditions.
