TRC for Citizens of the United Kingdom and Ireland
Poland remains one of the key migration destinations for citizens of the United Kingdom and Ireland. The reasons include a stable labor market, growing business opportunities, relatively low cost of living, and a central location in Europe. At the same time, after Brexit, the legal situation of UK citizens has changed significantly. In practice, this causes many questions and misunderstandings. These arise when planning relocation or long-term residence.

It is important to emphasize right away that citizens of Ireland and the United Kingdom cannot currently be treated the same under migration law. Ireland remains within the structures of the European Union. In contrast, the United Kingdom is treated as a third country. However, an exception exists for individuals covered by the EU–UK Withdrawal Agreement.
Correctly determining the legal status at the beginning of the process helps avoid problems with the legality of residence, employment, business operations, or obtaining permanent residence in the future.
Status of Irish Citizens in Poland
Irish citizens benefit from the freedom of movement within the European Union. This means that the procedure for legalizing residence is much simpler than for third-country nationals.
A stay of up to 90 days does not require any administrative formalities beyond having a valid ID or passport. During this time, an Irish citizen can travel freely and reside in Poland. In addition, they can undertake organizational activities related to relocation or starting work.
If the stay exceeds 3 months, there is an obligation to register the EU citizen’s residence at the voivodeship office appropriate for their place of residence. Registration is not a residence permit in the sense of the classical residence card for non-EU foreigners. Instead, it is a formal confirmation of the right of residence under EU law.
Grounds for Residence Registration
- Employment in Poland
- Running a business
- Possession of financial means and health insurance
- Studies with financial and insurance coverage
- Residence with a family member who is a citizen of Poland or the EU
After 5 years of legal and uninterrupted residence, an EU citizen acquires the right to permanent residence in Poland.
Status of UK Citizens after Brexit
For UK citizens, the key factor is the start date of residence in Poland. In practice, there are two main legal scenarios.
The first concerns individuals who legally resided in Poland before December 31, 2020, and continue to live here. These individuals can benefit from the rights under the Withdrawal Agreement between the United Kingdom and the European Union. In practice, this means retaining the right to reside. It also means retaining the right to work and operate a business on terms similar to those of EU citizens.
In such cases, it is recommended to obtain a new residence document confirming the status of a Withdrawal Agreement beneficiary. This document does not create the right of residence but confirms its existence. Moreover, it significantly facilitates daily administrative functioning.
The second scenario concerns UK citizens who arrived in Poland after January 1, 2021, or do not meet the conditions of the Withdrawal Agreement. In such cases, they are treated as third-country nationals. As a result, they are subject to standard migration procedures.
If the planned stay exceeds 90 days, it is necessary to obtain the appropriate residence title, most often a temporary residence permit.
Common Grounds for Temporary Residence
The most commonly used grounds for residence legalization include employment, running a business, family residence, and business-related residence.
It is crucial to demonstrate real employment and compliance with wage and working conditions requirements.
For business activity, it is necessary to show the real operation of the company, revenue, or business potential. This is especially important for business residence permit applications in Poland.
Family residence includes:
- Marriage to a Polish citizen
- Reunification with family in Poland
- Residence permit based on marriage in Poland
Business residence concerns, among others:
- Board members of companies
- Foreign investors
- Employees seconded to work in Poland
For employment, the basis is an employment contract, civil law contract, or B2B cooperation. It is crucial to demonstrate real employment and compliance with wage regulations.
For running a business, it is necessary to show the actual functioning of the company, revenues, or economic potential of the business.
Family residence mainly involves marriage to a Polish citizen or a legally residing foreigner.
Business residence may involve board members, investors, or employees seconded to Polish branches of foreign companies.
Formal Requirements When Submitting an Application
Typically required documents include:
- Valid passport
- Biometric photos
- Proof of the purpose of stay
- Proof of financial means
- Proof of health insurance
- Document confirming place of residence
Depending on the grounds of residence, the office may require additional documents.
Criminal Record Certificate
A certificate from the National Criminal Register (Krajowy Rejestr Karny, KRK) is an official document confirming the absence of entries in Polish criminal registers. This document is often required by employers, public institutions, and immigration authorities. In particular, it is important for UK & Ireland citizens planning to work, relocate, legalize residence, or start a business in Poland.
In many procedures, such as background checks, employment verification, residence permit applications, or professional licensing in Poland, the criminal record certificate is a key part of the documentation.
The certificate can be obtained in the following ways:
- In person at the KRK office – recommended for urgent administrative matters
- Through a proxy – convenient for foreign nationals residing outside Poland
- By post – for individuals unable to submit the application in person
In practice, the waiting time for a Polish Criminal Record Certificate usually ranges from a few working days up to 2–3 weeks. This depends on the method of submission, current office workload, and document accuracy.
ONE PLUS provides comprehensive support in obtaining the KRK certificate for foreign clients, including UK and Irish citizens. The standard processing time with ONE PLUS support is usually 14 to 20 calendar days. It depends on individual circumstances and document completeness.
Common Mistakes
The most frequent problems include:
- Incorrect assumption that a UK citizen is still treated as an EU citizen
- Exceeding the permissible period of stay without submitting an application
- Confusing registration with legalizing residence
- Submitting incomplete documentation
- Lack of a long-term residence strategy
Strategic Planning for Residence Legalization
From the perspective of migration consulting, the optimal process includes analyzing the residence history, selecting the proper legal basis, preparing complete documentation, and planning a long-term path.
In many cases, the ultimate goal is permanent residence or Polish citizenship. Therefore, the strategy should be built in advance.
Importance of Individual Case Analysis
Every migration case is unique. Important elements include residence history, family situation, income source, employment status, and long-term plans.
Therefore, in practice, professional legal analysis at the beginning of the process often saves many months of administrative proceedings. It also helps avoid the risk of refusal.
