Bringing Your Family on a PhD or Researcher Visa: What to Check

Many PhD positions in Europe come with a residence permit for a researcher, not a student visa. If you have a spouse, partner, or children, you can often bring them with you. The exact rules depend on the country. This guide explains the general pattern. It uses the current rules in Sweden and the Netherlands as examples. Always check the official immigration page for your own country before you apply; rules and amounts change.

Who counts as "family" on a researcher visa

Most countries use a similar, narrow definition of family for a researcher's permit: a spouse, a registered partner, or a cohabiting partner, plus minor children. The exact age limit for children is not the same everywhere.

In Sweden, the Migration Agency's family category for a researcher's relatives covers a spouse, a cohabiting partner, a registered partner, and unmarried children under 18. This is a lower age limit than the category for an employee's family, which covers unmarried children under 21.

In the Netherlands, the rules depend on how you arrived. If you already hold a researcher permit from another EU country and move to the Netherlands for 180 days or fewer, your family members can travel with you without a separate Dutch permit, as long as their own residence permit from the first EU country stays valid. If you come to the Netherlands directly, your partner applies for an ordinary residence permit for a partner, under its own age and income rules.

Sweden: how the Migration Agency handles family

If you apply for a residence permit to do research in Sweden, your family can apply for their own permits at the same time, according to the Swedish Migration Agency. Each family member needs a valid passport.

For a researcher's family, Sweden does not apply the same maintenance requirement that it applies to the family of an employee. Instead, the family member must show enough money for the whole stay. When we checked the Migration Agency's page, the stated minimum was about 4,440 Swedish kronor a month for an adult, and about 2,664 kronor a month for each child. Check the current figures on the Migration Agency's page before you apply, because the agency updates them.

The Netherlands: how the IND handles family

The Dutch Immigration and Naturalisation Service (IND) separates two cases.

Short-term mobility (180 days or fewer), coming from another EU country. If you already hold a valid researcher permit in another EU state, under Directive (EU) 2016/801, and you move to the Netherlands for research, your family does not need a Dutch residence permit. You must send the IND a notification about your family's arrival yourself; the researcher is the only one who can submit it.

All other cases. Your partner applies for an ordinary residence permit to join you. The IND's general requirements for a partner permit include:

both partners are 21 or older (18 or older if you were already married before moving to the Netherlands)
you can show a verifiable relationship: marriage, a registered partnership, or an unmarried partnership
you and your partner will register at the same address with the municipality
you meet the IND's income requirement as the sponsor
your partner may need a tuberculosis test after arrival, and a civic integration exam abroad before the provisional visa (MVV), unless an exemption applies

When we checked the IND's page, the application fee was €254 for the permit and MVV together. The IND must decide within 90 days of a complete application, though it can extend this period if it needs more time or information. If you hold a residence permit as a researcher under Directive (EU) 2016/801, your partner is normally free to work in the Netherlands without a separate work permit.

What it costs and how long it takes

Costs and processing times change often, and they are set by each country, not by the EU. As a general rule, budget for:

a visa or permit application fee per family member
translation and legalisation of documents such as marriage or birth certificates
possible costs for a civic integration exam, a TB test, or biometric appointments

Always check the current fee schedule on the country's own immigration website before you budget or apply.

Documents your family needs

Prepare these documents early, since translation and legalisation take time:

Document	Note
Valid passport for each family member	Check the minimum remaining validity the country asks for
Marriage or partnership certificate	Often needs an official translation and legalisation
Proof of the researcher's position or permit	A hosting agreement, employment contract, or permit decision
Proof of sufficient funds	The amount and the proof required differ by country
Birth certificates for children	Needed to confirm the relationship and the child's age

Common mistakes to avoid

Assuming the same age limit for children applies in every country; it does not.
Applying for a standard family reunification visa when a simpler researcher-family route exists, or the other way round.
Forgetting that a partner's right to work can depend on the main applicant's exact permit type.
Leaving document translation and legalisation until the last weeks before travel.
Not checking whether the family application must be submitted by the researcher, not the family member.

Where to check the rules for your country
