Document Services in Poland for Foreigners
ONE PLUS helps foreigners obtain official documents in Poland and abroad without unnecessary bureaucracy, confusing procedures, or multiple visits to government offices.
For many people, the most stressful part of living abroad is not applying for a residence permit, citizenship, university admission, or a new job. The real challenge begins when an authority suddenly requests a document you have never heard of before.
- A criminal record certificate.
- An apostille.
- A sworn translation.
- A notarized power of attorney.
- A duplicate birth certificate from Ukraine.
- Information from the Schengen Information System (SIS).
Many foreigners only discover these requirements after receiving a letter from a government office, an employer, a university, a bank, or a consulate. At that point, deadlines become critical, procedures become confusing, and finding reliable information becomes difficult.
This is exactly where ONE PLUS helps.
For more than a decade, we have been assisting foreigners throughout Poland with obtaining documents, legalizing paperwork, arranging sworn translations, coordinating notarial procedures, and preparing documentation for immigration, citizenship, employment, education, and international legal matters.
Our office is located in Wroclaw, but we work with clients from every region of Poland and from dozens of countries worldwide. Most procedures can be completed remotely without your personal presence.
Today, our experience is reflected in more than 370 verified Google reviews and recognition as Orły Prawa 2026, one of Poland’s most respected legal industry awards.
When One Missing Document Can Delay Everything
Most clients contact us because they have already encountered a problem.
Perhaps the Voivodeship Office requested additional documentation for a residence permit application.
Perhaps a foreign employer requires a Polish criminal background check.
Perhaps a university refuses to accept a diploma without apostille legalization.
Perhaps a consulate requires certified translations.
Or perhaps important documents were lost years ago and now need to be recovered urgently.
In theory, every document has a procedure.
In practice, the problem is much bigger.
Clients often do not know:
- which authority issues the document;
- whether the document is still valid;
- whether apostille legalization is required;
- whether a sworn translation is necessary;
- whether the document will be accepted abroad;
- how long the procedure takes;
- whether personal attendance is required.
Mistakes can lead to delays, additional requests from authorities, rejected applications, missed deadlines, and unnecessary expenses.
Our role is not simply to obtain a document.
Our role is to make sure the document is prepared correctly, accepted by the receiving authority, and delivered on time.
Criminal Record Certificates and SIS Information
One of the most frequently requested documents among foreigners is a criminal record certificate.
It may be required for:
- residence permit applications;
- citizenship procedures;
- visa applications;
- employment;
- professional licensing;
- immigration processes abroad;
- business registration;
- compliance procedures.
Many clients also need to verify whether information about them exists in European security databases before starting immigration procedures.
ONE PLUS helps obtain official certificates directly from the competent authorities and coordinates apostille legalization and certified translations when necessary.

Notary Services and Powers of Attorney
Many important legal procedures cannot be completed without notarized documents.
This often includes:
- powers of attorney;
- signature certification;
- notarized copies;
- declarations and authorizations;
- documents intended for use abroad.
For foreigners, the biggest challenge is usually not the notary appointment itself.
The challenge is understanding exactly what document is needed and ensuring it complies with the requirements of the institution that will receive it.
Because ONE PLUS works closely with a Polish notary, we help clients prepare documentation correctly before the appointment, reducing the risk of mistakes and rejected paperwork.

Sworn Translation Services
Many administrative procedures require more than a standard translation.
Polish authorities, courts, universities, banks, insurance companies, and immigration offices often require sworn translations prepared by certified translators officially registered with the Ministry of Justice.
A single translation error can create significant problems.
Incorrect personal data, inaccurate legal terminology, or inconsistencies with the original document may result in additional requests from authorities or delays in processing.
ONE PLUS coordinates sworn translations in numerous language combinations, including English, Polish, Ukrainian, Russian, German, Spanish, French, Italian, and many others.
Before a document is translated, we verify whether a sworn translation is actually required, helping clients avoid unnecessary costs.

Apostille and International Document Legalization
Many people assume that once a document has been issued, it can immediately be used abroad.
Unfortunately, this is often not the case.
Government authorities, universities, employers, courts, and consulates frequently require apostille legalization before accepting foreign documents.
Without proper legalization, even a perfectly valid document may be rejected.
Before starting the process, our specialists verify:
- the country where the document will be used;
- current legalization requirements;
- translation requirements;
- authority-specific rules;
- additional certification requirements.
This approach helps clients avoid repeated procedures, unnecessary expenses, and costly delays.

Ukrainian Document Recovery and Archive Searches
Thousands of Ukrainians living abroad face difficulties because important documents have been lost, damaged, or remain inaccessible.
Some clients possess only scans or photographs that are not accepted by government authorities.
Others require official records that were issued years ago and are no longer available locally.
ONE PLUS assists with obtaining:
- birth certificates;
- marriage certificates;
- divorce records;
- death certificates;
- criminal record certificates from Ukraine;
- driver’s licence legitimacy certificates;
- archive records;
- apostille legalization;
- other official documents and extracts.
Most procedures can be completed remotely without travelling to Ukraine.
For many clients, this becomes the fastest and safest way to recover important documents while living abroad.
