About ONE PLUS

For over 10 years, we have been helping foreigners legalize their stay, handle documents, and open a business in Poland. During this time, we have guided thousands of clients from different countries — from the first consultation to receiving ready documents and successfully launching a business.

Every case is handled by a qualified specialist personally — we never pass cases to intermediaries. We interact with government authorities daily and monitor changes in legislation, finding effective solutions even in complex situations.

Over the years, we have employed over 8,000 foreigners and completed projects with a turnover exceeding 30 million zloty.

Our goal is not just to process paperwork, but to find the optimal solution for your specific situation: quickly, legally, and without unnecessary stress.

Client trust is the highest measure of our success

Needed a certificate of no criminal record for a job offer in Poland. ONE PLUS filed it for me and I collected the document two days later.

27.08.2026

My police clearance was for a residence card application. I would have picked the wrong form on my own, they explained which one and it came back on time.

24.08.2026

Got my criminal record certificate through ONE PLUS in Wroclaw. They filed the same day I called and told me the real cost upfront. No queues, no guessing which office to visit.

21.08.2026

Everything went very smoothly and I’m very grateful. I’ll definitely get in touch with you again if the need arises.

26.08.2026

I ordered a sworn translation, everything went quickly and to a high standard, I’ll definitely contact you again.

25.08.2026

Comprehensive help with documents in Poland, they prepared Aneks 1, found suitable insurance and did the sworn translations, thank you very much.

25.08.2026

Individual consultations on legalisation, advice on how to properly change employers during a case without wasting time.

25.08.2026

We asked for help getting a residence permit. From the very start we received detailed advice on legalisation and the documents needed in Poland.

24.08.2026

I’m very happy with the help. I needed advice on legalisation and registering my residence card in Poland. They helped me sort out my documents, checked everything and explained what to do and how. Thanks to them the whole process went much more smoothly. I recommend them!

24.08.2026

We asked for advice on legalising our stay in Poland and getting a residence card. Everything was explained clearly, they helped with the paperwork and were with us at every stage. They helped us get our residence card fairly quickly, in about 4 months. I’m very grateful for the professional help!

24.08.2026

Very useful legal advice. My wife and I came with a few questions about our stay in Poland and got clear, specific answers to everything we wanted to know.

24.08.2026

I had to exchange my driving licence for a Polish one. They helped me take care of all the formalities and explained exactly what I needed to do.
