What Is MOS (Modul Obslugi Spraw)?
MOS — Modul Obslugi Spraw, or “Case Handling Module” — is the official online portal of Poland’s Office for Foreigners (UDSC) for submitting residence-permit applications, including the Temporary Residence Card (TRC). It runs at mos.cudzoziemcy.gov.pl and is available in seven languages: Polish, English, Ukrainian, Russian, French, Arabic, and Vietnamese.
Instead of mailing a paper form to your Voivodeship Office, you create an account, complete the application on screen, upload scans of your documents, and submit electronically. The system checks for missing information as you go and shows contextual hints — directly targeting the incomplete-file errors that stalled so many cases under the old paper process.
Is MOS Mandatory in 2026?
Yes. MOS 2.0 went live at 00:01 on 27 April 2026 and is now the only accepted channel for most residence applications. The launch date was announced 14 days in advance, as the law requires. Paper applications that were not physically received by the Voivodeship Office before the cut-off are left without examination — the postmark date does not count.
| Application type | Filed through MOS? |
|---|---|
| Temporary residence permit (TRC / Karta Pobytu) | Yes — mandatory |
| Permanent residence permit (pobyt staly) | Yes — mandatory |
| EU long-term residence permit | Yes — mandatory |
| Appeal against a decision (odwolanie) | No — on paper or via e-Doreczenia |
| Replies and document requests during your case | No — on paper or via e-Doreczenia |
What You Need Before You Start
Trusted Profile (Profil Zaufany): MOS logs you in through Poland’s national single sign-on. Set up your Profil Zaufany at gov.pl first — without it you cannot submit.
A personal account: The MOS account is personal. A lawyer or representative cannot create it for you, and accounts from the old MOS system do not transfer — you register fresh.
Your passport: A clear scan of the photo page plus any relevant visas or stamps.
A digital biometric photo: One digital photo to the official specification — not the two paper photos the old process required.
Supporting documents: Scans of everything for your permit type — contract and Appendix 1 for work, enrollment certificate for study, proof of accommodation, health insurance (50,000 EUR minimum cover), and financial proof (1,010 PLN/month for a single applicant).
For the full document list by permit type, see the TRC Document Checklist.
How to Apply Through MOS: Step by Step
| Step | What you do |
|---|---|
| 1. Create account | Register at mos.cudzoziemcy.gov.pl and log in with your Trusted Profile. |
| 2. Choose permit | Select the permit type (temporary, permanent, EU long-term) and the legal ground — work, study, business, or family. |
| 3. Fill the form | Complete every field. The interface is multilingual, but the application data itself must be entered in Polish. |
| 4. Upload documents | Add scans of your passport, photo, and supporting papers within the file-size limits below. |
| 5. Employer signs | For work cases, your employer signs Appendix 1 and annexes digitally through an email link the system sends — valid for 30 days. |
| 6. Submit | Review carefully, then submit. An application cannot be edited or cancelled once submitted. |
| 7. Give biometrics | Attend your in-person appointment at the Voivodeship Office for fingerprints. MOS does not replace this visit. |
MOS Upload Requirements
| Item | Limit |
|---|---|
| Photo file | up to 2.5 MB |
| Single document file | up to 10 MB |
| All files combined | up to 50 MB |
| Application language | Polish |
Documents in another language generally need a sworn (przysiegly) translation. Scan in good quality — an illegible upload is a common reason for the office to request corrections, and each round trip adds weeks.
MOS Rules You Must Know
Submissions are final: You cannot edit or withdraw an application after submitting, so check every field before you confirm.
The office does not reply inside MOS: Official decisions and any request for documents arrive on paper or through e-Doreczenia, not in the portal. Set up e-Doreczenia so you never miss a deadline.
Appeals are separate: A rejection is appealed on paper, not through MOS — see how to appeal a TRC rejection.
If the system is down on your last legal day: You have 3 business days after service is restored to submit, and the filing date counts as the first day of the outage. Keep a screenshot as proof.
MOS vs the Old Paper Process
| Old paper process | MOS online |
|---|---|
| Mail or hand in printed forms | Submit electronically at mos.cudzoziemcy.gov.pl |
| Two paper photos (35×45 mm) | One digital biometric photo |
| Postmark date treated as the filing date | Only applications received in the system count |
| Clerk checks completeness by hand | Real-time hints and missing-field checks |
| Corrections possible before processing | No edits or cancellation after submission |
Common MOS Mistakes (and How to Avoid Them)
Burman Robinson, a Warsaw immigration firm that has handled over 5,000 TRC cases since 2017, reports that the most frequent MOS errors are entering application data in English instead of Polish, uploading a photo that fails the biometric specification, and missing the 30-day window for the employer to sign Appendix 1. In their experience, applications that are complete and correct on first submission clear the biometric stage noticeably faster than cases the office has to send back for corrections.
After You Submit
You will be called to your Voivodeship Office in person to give fingerprints. If you filed before your previous permit expired, your legal stay is protected while the case is pending. The decision is delivered through e-Doreczenia — an unopened electronic letter is treated as delivered after 14 days, so check it regularly. Processing times still vary widely by region; see processing times by voivodeship and the full cost breakdown.
