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.

- Personal and professional approach to every client and case
- Full legal support from consultation to document receipt
- Guaranteed confidentiality and transparency at every stage
- Deep knowledge of Polish law and years of successful practice
