Family Reunification in Poland — Joining a Spouse, Child or Parent in 2026

Family reunification is one of the most common grounds for obtaining a residence card in Poland — but the conditions differ depending on whether the person the foreigner wants to join (the "sponsor") is a Polish citizen or also a foreigner. Here is what to check in 2026.

Two paths: joining a Polish citizen and joining a foreigner

The Act on Foreigners provides for two separate temporary residence permits based on family ties. The first applies when the sponsor is a Polish citizen (a spouse, or a parent of a minor child holding Polish citizenship). The second applies when the sponsor is a foreigner legally staying in Poland (a spouse, parent or adult child). This second path has an additional condition concerning the sponsor themselves, described below.

Spouse of a foreigner — the sponsor's stable-residence condition

If the person the foreigner wants to join is another foreigner, the law requires the sponsor to meet one of the following conditions (art. 159(1) of the Act on Foreigners):

• hold a permanent residence permit, an EU long-term resident permit, refugee status or subsidiary protection, or
• have been residing in Poland continuously for at least 2 years on the basis of consecutive temporary residence permits directly before filing the application, with their current permit issued for a period of at least one year.

This is a common point of confusion: it is not about how many years the sponsor's residence card is still valid for, but about how long the sponsor has already been living in Poland on consecutive permits. A short, freshly issued residence card, preceded by earlier years of legal residence, can be entirely sufficient — and conversely, a card valid for many more years will not help if the sponsor has only recently started living in Poland.

Spouse of a Polish citizen — a different, simpler condition

When the sponsor is a Polish citizen, the 2-year residence condition does not apply. What matters instead is proving that the marriage is genuine and that the spouses lead a shared life — the voivodeship office may verify this through, among other things, joint registration, joint photographs, correspondence, or an interview with the couple.

A child joining a parent in Poland

The rules depend on the child's age on the day the application is filed:

• Under 18 — the application is processed without additional conditions beyond a birth certificate and proof of the family tie.
• 18–25 — the child must still be studying (any mode: full-time or part-time) — a certificate from the school or university is enough.
• 26 or older — the parent's maintenance obligation has in principle ceased, and the office treats the applicant as capable of self-support regardless of whether they are still studying. If the adult child has no income of their own, a maintenance annuity agreement registered with the tax office between the parent and the child is required — the parent's general income documents alone are not enough.

Health insurance for a child co-insured under a parent (via a ZUS ZCNA registration) is possible only until the child turns 26, and only until 18 if the child is not studying. An older applicant needs their own title to insurance or a private policy.

A parent joining an adult child

When a parent applies to join an adult child living in Poland, the office primarily checks the genuine maintenance of family ties and shared family life (e.g. living together, regular contact, support) and the parent's source of maintenance — which may be the child's income or that of the child's spouse. If anyone's surname has changed in the meantime (e.g. through marriage), this must be documented so the office can trace the continuity of identity.

Which documents to prepare

The basis is always a document confirming the family tie — a marriage certificate or a birth certificate. If issued abroad, it usually requires a sworn translation and an apostille or consular legalisation. The exception is countries with which Poland has a bilateral legal-assistance treaty (including Belarus, Ukraine and Russia) — there, a sworn translation alone is enough, without an apostille. The office also expects evidence of shared family life (photographs, correspondence, proof of living together) and documents confirming a stable source of income sufficient to support the family — its exact amount is assessed individually under current regulations, so it is worth checking before filing.

How to file the application

Applications for temporary residence based on family ties are filed electronically through the Case Handling Module (MOS) at cudzoziemcy.gov.pl, which requires a PESEL number and a Profil Zaufany (Trusted Profile) or an electronic signature. Current requirements and forms are also available on the website of the Office for Foreigners. Every family's situation is different — the children's ages, the country that issued the certificates, the sponsor's residence history — so it is worth consulting the exact document list with a lawyer before filing.
