It's 9pm on a Sunday and you've just realized your work permit expires in six weeks. You Google "karta pobytu application Poland" — and up comes a stack of forum posts from 2024 telling you to print your forms, show up in person at the urząd, and wait in a queue at 7am. None of that exists anymore. Since April 27, 2026, every karta pobytu (Polish residence permit) application must go through MOS — Moduł Obsługi Spraw — an online government portal. No paper. No queue to file. The karta pobytu online process through MOS is now the only legal route for most foreigners in Poland.
What Is MOS and Why It Changed Everything on April 27, 2026
MOS — Moduł Obsługi Spraw — is the Polish government's centralized online portal for residence permit applications. It went fully live on April 27, 2026, and from that date forward, applications for temporary residence (pobyt czasowy), permanent residence (pobyt stały), and EU long-term resident permits must be submitted exclusively through mos.cudzoziemcy.gov.pl. Paper applications received after April 26, 2026 — regardless of postmark date — are not examined. They are left without consideration.
This is not a pilot programme. It is not optional. The law changed. If you filed on paper before that cutoff and your application arrived at the voivodeship office by April 26, you are fine — your case continues under the old rules. If it arrived later, you need to refile electronically.
There are narrow exceptions — notably intra-corporate transfer (ICT) permits, certain family reunification cases where the applicant is outside Poland, and applications involving family members of EU/EEA, Swiss, or UK citizens. For the vast majority of foreign workers from India, Bangladesh, Sri Lanka, Nepal, the Philippines, and Nigeria, MOS is now your only option.
The portal is available in seven languages: Polish, English, Ukrainian, Russian, French, Vietnamese, and Arabic. If Polish bureaucracy has never been your comfort zone, the English interface is fully functional. You can also check the official UDSC guide for additional clarifications on what the portal covers.

Before You Open MOS: The One Thing That Blocks Most Applicants
You cannot sign or submit anything in MOS without a Profil Zaufany — Poland's free digital identity system. It is the electronic signature the government accepts. Without it, you can browse MOS, even fill in a form, but you cannot submit.
To get a Profil Zaufany you need a PESEL number. Most foreign workers legally residing in Poland already have one — it's issued when you register your address at your local urząd gminy. If you don't have a PESEL yet, getting it is your first stop.
Once you have a PESEL, setting up Profil Zaufany takes about 15 minutes at login.gov.pl. You confirm your identity either through your Polish bank's online login (most major banks support this — PKO BP, mBank, Santander, ING, Pekao) or in person at a confirmation point (ZUS office, post office, or voivodeship office). The bank route is fastest — if your salary lands in a Polish bank account, you can be verified the same day.
One more thing before you log in: you need a current digital photograph that meets the Polish biometric photo standards — 35x45mm proportions, white background, face filling 70-80% of the frame, no glasses, neutral expression. The system will reject uploads that don't meet these specs. Check our detailed breakdown at 3 Photo Mistakes That Get Karta Pobytu Files Rejected in 2026 before you scan anything.
The MOS Application: Step by Step, Start to Submission
Here is the actual process once you have your Profil Zaufany and documents ready.
- Go to mos.cudzoziemcy.gov.pl and click "Złóż wniosek" (Submit application). Log in via login.gov.pl using your Profil Zaufany credentials.
- Create your MOS account or log into an existing one. Add your email address — this is where case notifications will arrive. Do not skip this step.
- Select the permit type. For most foreign workers: "Zezwolenie na pobyt czasowy i pracę" (temporary residence and work permit — single permit). The stamp duty for this type is PLN 440.
- Fill in the application form. The portal guides you section by section: personal data, grounds for stay, employment details, accommodation address. Answer every field — incomplete forms generate "wezwanie do uzupełnienia" (requests to supplement), which pause your clock.
- Upload your documents as clear scans or photos. Every page of your valid passport, your digital photo, proof of accommodation (e.g. rental agreement), proof of employment (employer's declaration or work contract), and health insurance confirmation.
- Sign the application using your Profil Zaufany. This is the legal equivalent of a wet signature. Once signed, the application is locked — you cannot edit it.
- Pay the stamp duty. PLN 440 for a single residence and work permit, or PLN 340 for a standard temporary residence permit without work authorization, goes to the voivode's bank account (details provided in the portal). PLN 100 for the physical card is paid separately later, after a positive decision. Payments are made outside MOS — bank transfer or in-person at the office cashier.
- Submit. You will receive a UPP confirmation number (Urzędowe Poświadczenie Przedłożenia) — save this. It proves your application was received and activates your legal stay while the case is pending.
Practical tip: Raj, a software engineer from Bangalore, submitted his first MOS application in May 2026. He attached 14 pages of passport scans but forgot the last empty pages. The office sent a supplement request — adding three weeks to his timeline. Scan every single page, including blank ones.
After Submission: Biometrics, the Stamp, and What the UPP Actually Protects
Submitting online does not mean you never visit the office. It means the filing itself is digital. Two things still require your physical presence.
First: biometrics. After your application is registered in MOS, the urząd schedules a fingerprinting appointment. You don't book this yourself — the office contacts you via the MOS portal or by registered eDoręczenia notification. In Warsaw, this slot can be 4-8 weeks out from submission. Bring your passport and the printed UPP. Missing this appointment can suspend your case.
Second: collecting the card. After a positive decision is issued, you pay PLN 100 and pick up the physical karta pobytu in person at the voivodeship office. The card is not mailed.
Between submission and collection, you are covered by a legal stamp (stempel) in your passport — the UPP confirmation triggers this protection. Your right to stay and work continues uninterrupted while the case is pending, even if your original visa or previous karta expires.

Documents the MOS Portal Needs — the List That Trips People Up
The portal's checklist is clear in theory. In practice, document errors account for the majority of supplement requests and delays. Here is what "correct" actually means for each item.
- Passport scan: every page including blank pages and the cover. PDF or high-resolution JPG. Must be legible — font on personal data page must be readable.
- Digital photo: current (taken within last 6 months), biometric spec, white background. If you are wearing a headscarf or turban for religious reasons, it is accepted — but your face from forehead to chin must be fully visible.
- Proof of employment: either your employment contract (umowa o pracę) or your employer's declaration (oświadczenie pracodawcy) on company letterhead, confirming your position, salary, and continuity of employment. For single permit applications, this is mandatory — not optional.
- Proof of accommodation: a signed rental agreement (umowa najmu) registered with the tax authority, or a declaration from your landlord. A hotel receipt does not qualify. A sublease agreement does qualify if the original lease allows it.
- Health insurance: NFZ (public) coverage confirmation, or a private policy covering at least the minimum required scope. If you are employed under umowa o pracę, your employer's ZUS enrollment automatically covers you — attach ZUS confirmation.
- Income evidence: pay slips for the last 3 months, or a salary statement from your employer. If your contract is new, a job offer letter plus proof of signing is typically accepted.
All documents in a language other than Polish must be accompanied by a certified translation. The MOS system itself will flag missing attachments before you submit, but it cannot judge document quality — that's a human reviewer's job. A blurry scan passes the upload screen and then gets flagged two weeks later.
Frequently Asked Questions
My Profil Zaufany keeps showing an error when I try to sign. What do I do?
The most common cause is a session timeout — MOS logs you out after 30 minutes of inactivity, but the Profil Zaufany signing window is separate and can expire faster. Solution: fill your form, save it as a draft, then open the signing step in a fresh browser session without other tabs consuming your session token. If you are using a VPN, disable it — the gov.pl authentication server sometimes blocks foreign IP ranges.
Can I apply through MOS if I don't have a PESEL yet?
No. A PESEL number is required to obtain a Profil Zaufany, which is required to sign and submit in MOS. If you are new to Poland and haven't registered your address yet, go to your local urząd gminy or urząd miasta first, register your place of residence (zameldowanie), and request a PESEL. The process typically takes 1-3 working days. Only then can you set up Profil Zaufany and proceed.
I submitted on paper in March 2026 — is my application still valid?
It depends on when the voivodeship office physically received it. If your paper application arrived at the urząd wojewódzki by April 26, 2026 (arrival date, not postmark), it is valid and will be processed under the previous rules. If it arrived on April 27 or later, it will not be examined regardless of when it was sent. You would need to refile electronically via MOS.
Do I need to pay the PLN 440 before or after submission in MOS?
The stamp duty must be paid before or at the time of submission, but it is not paid inside the MOS portal. You transfer PLN 440 (for a single residence and work permit) to the voivode's designated bank account, attach the transfer confirmation to your MOS application as a scan, and include the reference number. The PLN 100 card issuance fee is paid separately, only after a positive decision is issued. Details on correct bank account numbers are shown inside MOS when you select your permit type. Check official UDSC fee information for the latest payment instructions.
My employer refused to sign the declaration for MOS. Can I still apply?
For a single permit (residence and work), the employer's declaration or signed contract is a required document. Without it, the office will send a supplement request and your case will stall. If your employer is refusing to cooperate, that is a red flag worth addressing quickly — an employer who won't sign a standard declaration creates bigger problems than just the MOS application.
