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

Second citizenship in 2026 is viewed by families as a "backup airfield": a strategy that allows an investor to obtain status not only for themselves, but also for a spouse, children, and in some programs — parents. A second passport opens up great opportunities for living, working, educating children, and passing on family assets.

Who is considered 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. Usually these are a spouse, children, and parents.

1. Spouse. The most common category of dependents. When submitting an application, a marriage certificate and documents for both spouses must be provided. If the couple is in a civil partnership or is a same-sex union, in that case citizenship cannot always be claimed (depending on the program). It is not enough for the application to simply state the fact of a relationship — legal recognition of it in the given jurisdiction is required.
2. Dependent Children. Minor children are another category included in the application. Simpler rules apply to them, and it is enough to confirm age (children under 18 are included without proof of financial dependency). When reviewing an application for adult children, the absence of their own income, full-time study, cohabitation, and the child's support by the applicants are taken into account. There is no age limit for children with disabilities.
3. Dependent Parents. This category is not included in every family application program, and when submitting one, age, financial dependency on the investor, and cohabitation are taken into account. To confirm dependency, documents (Proof of Dependency) may be required: absence of personal income, evidence of bank transfers from the investor, documents confirming cohabitation, proof of the relationship, and pension documents.

A passport by investment for children and parents (dependents) varies by country: in one case documentary proof of the relationship is sufficient, while in another — for adult children and parents — financial dependency must be proven. It is important to distinguish between residency programs and Citizenship by Investment. For example, in Turkey or the Caribbean, citizenship can be obtained through investment requirements, while in Italy, Spain, or Greece the Golden Visa is a path to residency and only naturalization upon meeting conditions. Each program has specific terms and requirements concerning financial dependency, the age of children, additional fees, and marriage requirements.

Comparison of countries by conditions for including family in a second citizenship application

Turkish citizenship for the entire family is one of the easiest ways to obtain a second passport: the investor buys real estate worth from $400,000 and goes through a simplified procedure to obtain a second passport, with family members able to be included in the application. A Caribbean passport for the investor, spouse, and children can be obtained with a smaller investment amount, but with a larger list of requirements and additional fees for each dependent. We invite you to review popular naturalization destinations and the program conditions that must be met when applying to include a relative.

Is it possible to add family members after obtaining a passport?

For many investors, the ability to add a family member to a second citizenship application after the passport has already been obtained is an important consideration. There are certain mechanisms for processing this. In the case of a newborn child, a separate procedure must be followed. Information must be submitted to the relevant authorities after birth, since the child's details cannot simply be added to the passport. A birth certificate and other documents are provided in accordance with the conditions of the specific country. A new spouse or parents who reach the required age later are checked separately. In cases where parents were not deliberately included in the application earlier, their processing may follow a different procedure.

How much does citizenship cost for a family of 4

For Caribbean programs and Turkey in 2026, obtaining a second passport involves not only the main investment amount, but also a number of related expenses in the form of government fees, checks, and additional charges. The final budget is made up of:

• the contribution or investment amount;
• the application filing fee;
• a fee for verification and processing of information;
• interview fee;
• document and legalization costs;
• agency and lawyer support;
• notary services;
• additional fees for family members.

Let's look at how much an application costs for a classic family model — Main applicant + spouse + 2 minor children.

Documents and Due Diligence verification for the family

Second-passport program options differ in their processing mechanisms. It is important to realistically assess your possibilities in terms of the family's full budget, the composition of Dependents, and Due Diligence requirements. For one family, for example, the ideal program will be one that allows the inclusion of adult children and parents, while for another — Turkey through real estate investment. For someone else, the European Golden Visa may be suitable as a long-term path to residency and naturalization. When documents are submitted, the competent authorities check not only the Main Applicant, but also the included Dependents. A basic document checklist:

• passports;
• birth/marriage certificates;
• adoption/guardianship documents;
• education documents;
• bank statements and information on the source of income;
• proof of residential address;
• police clearance certificates;

• Proof of Dependency for dependent adults.

The origin of the invested funds, as well as the presence of any negative information about relatives, is thoroughly checked. If violations are discovered involving any family member, this may lead to additional inquiries or negatively affect the application. When it comes to a child over 18, documents confirming full-time study, absence of independent income, and information on money transfers from parents can be provided.

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

A separate algorithm and approach to obtaining citizenship applies to European programs. The "Golden Visa" is not second citizenship. By investing in the Greek economy, the investor only obtains grounds for residency, but it does not guarantee a second passport. The applicant's family can also obtain the right to long-term residence, and citizenship can subsequently be acquired by fulfilling the state's naturalization requirements. In Italy, obtaining a second passport also happens through residency. For family reunification, the law allows a spouse, financially dependent children, and parents to be included upon meeting the conditions. Important: in Spain, the Golden Visa regime has been discontinued for new investors. Hayat Estate provides the services of qualified specialists in finding and purchasing real estate abroad.

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

Are parents allowed to be included?

For programs with a Dependent Parents category, it is allowed upon confirmation that the conditions are met.
