It's a Tuesday evening. Your current karta pobytu (Polish residence permit) expires in 89 days. You've been telling yourself you'll sort it out — and now you're Googling whether you still need to queue at the urząd or whether this MOS thing actually works. The answer: since 27 April 2026, paper applications are gone. Every renewal for a temporary residence permit in Poland goes through MOS — the Moduł Obsługi Spraw portal at mos.cudzoziemcy.gov.pl. No physical queue, no courier envelope, no wondering if the post office delivered your documents in time. The system is live, it works in English, and you can file from your phone at 11pm. This guide walks you through every step, every fee, and every mistake people make on their first MOS submission.
What Is MOS and Why It Changed Everything After April 2026
MOS — short for Moduł Obsługi Spraw — is Poland's official online portal for filing residence permit applications. The address is mos.cudzoziemcy.gov.pl, run by the Urząd do Spraw Cudzoziemców (Office for Foreigners). As of 27 April 2026, submitting a karta pobytu renewal application by post or in person at the office window is no longer accepted. If a paper envelope arrived after that date, it was returned unprocessed — regardless of when it was mailed. That caught a lot of people off guard.
The portal runs in 7 languages: Polish, English, Ukrainian, Russian, French, Arabic, and Vietnamese. That covers most of our clients. You log in with a Profil Zaufany (Trusted Profile) — think of it as Poland's government-verified digital ID. If you don't have one yet, setting it up takes about 20 minutes through login.gov.pl, and you can verify your identity at any Polish post office or bank branch with an in-person confirmation.
The big shift: MOS replaced the old InPol system used by Mazowieckie and several other voivodeships. InPol is gone for residence permit purposes. If you're in Warsaw, Kraków, Wrocław, Poznań — it's MOS now, full stop. For a deeper look at what this means for your specific voivodeship, see our Karta Pobytu Wait Times by Voivodeship in 2026.

Step-by-Step: How to Renew Your Karta Pobytu Through MOS
The process has seven stages. Miss any one of them and you risk delays — or worse, a request for supplementary documents that adds months to your wait.
- Set up your Profil Zaufany (if you don't have one). Go to login.gov.pl. You need a Polish phone number and a bank account, OR you can verify in person at a post office. Do this at least 2 weeks before your application deadline.
- Log in to MOS at mos.cudzoziemcy.gov.pl. Select 'Złóż wniosek' (Submit application). Choose your permit type — for most employment-based renewals, that's 'Zezwolenie na pobyt czasowy i pracę' (temporary residence and work).
- Fill in the application form. The form has around 11 sections covering personal data, employer details, accommodation address, and travel history. Take your time — errors here are the most common cause of supplementary-document requests (wezwanie do uzupełnienia braków).
- Upload your documents. MOS accepts PDF, JPG, PNG. Each file must be under 5 MB. The system will list which attachments are mandatory — don't skip optional ones if they apply to your case (they often do).
- Pay the PLN 340 stamp duty (opłata skarbowa). Payment is made by bank transfer to your voivode's account — the MOS system will show you the exact account number and reference code. Do NOT pay until you have the reference code from the system. Keep the transfer confirmation as proof.
- Submit and download your UPO. After submission, MOS generates a UPO — Urzędowe Potwierdzenie Odbioru, the official receipt. This document replaces the old passport stamp. While your case is pending, the UPO proves you have a legal right to stay in Poland. Carry a printed copy or have it on your phone.
- Attend your biometrics appointment. MOS will notify you of a date to appear at the urząd for fingerprints and a photo. In Warsaw, this slot can take 4–8 weeks to arrive. In smaller cities, it's faster. You cannot skip this step — the physical karta pobytu card requires biometric data.
The PLN 440 Fee Breakdown — Where Each Złoty Goes
There are exactly two government fees for a karta pobytu renewal. No hidden charges, no regional surcharges — just these two.
- PLN 340 — opłata skarbowa (stamp duty). Paid at the time of submission, by bank transfer to the voivode's designated account. This is the administrative fee for processing your application. Non-refundable even if the decision is negative.
- PLN 100 — opłata za wydanie karty pobytu (card issuance fee). Paid when your application is approved and you go to collect the physical card. This covers production and personalisation of the plastic card itself.
Total: PLN 440. Confirmed via the official fee schedule at gov.pl/web/udsc/informacje-o-oplatach. If anyone quotes you a different number — a third-party 'processing fee', an 'express surcharge' — that is not a government fee. For a full breakdown of every fee associated with the karta pobytu process, including translation costs and photo requirements, see our Real Cost of Karta Pobytu in 2026.
One timing note: pay the PLN 340 only after the MOS system generates your unique payment reference code. Paying before you have this code — or paying to the wrong voivode account — is one of the most common errors we see. The application then gets flagged as unpaid, and you're asked to re-submit proof. It adds weeks.
Practical tip: Screenshot or download your MOS payment reference code before closing the browser tab. The UPO document and the payment reference code are the two things you need to prove your application is valid and pending. Lose either one and you're making extra trips to the urząd.
What Documents Do You Actually Need to Upload?
The MOS system shows a dynamic document list based on your permit type and answers in the form. That said, for a standard employment-based karta pobytu renewal, expect to upload the following. For the official full checklist, check gov.pl/web/cudzoziemcy.
- Completed application form (generated by MOS — do not use old paper forms).
- Valid passport — scan of the biographic page plus all pages showing Polish entry/exit stamps and any visas. MOS will ask for all relevant pages.
- Proof of accommodation in Poland. This can be a rental agreement, confirmation letter from your landlord, or an owner's declaration (oświadczenie właściciela). The address must match what you entered in the form.
- Employer's document — typically the annex to your work permit (załącznik do zezwolenia na pracę) or, if on a single permit, the existing permit itself. Your employer may also need to submit a statement of intent to continue employment.
- Proof of income / payslips for the last 3 months. MOS does not specify a minimum income threshold for most temporary residence renewals, but the officer reviews whether you can support yourself. Consistent employment history helps significantly.
- Health insurance confirmation. This can be ZUS coverage letter (if employed under umowa o pracę) or a private policy certificate. Your ZUS status can be verified at zus.pl.
- Payment confirmation for PLN 340 (bank transfer receipt with your MOS case reference number).
Students renewing on a study permit need a different set: university enrollment confirmation, payment of tuition fees proof, and sometimes a statement from the dean's office. The MOS form will prompt you for the correct documents once you select the permit category.
Common Mistakes That Cost People Months in 2026
We handle a lot of renewals. Here's what goes wrong on MOS applications more than anything else:
- Applying too late. You must submit before your current karta pobytu or visa expires. The legal rule: submit while your status is valid, and the UPO keeps you legal during processing. If you miss the deadline and your card expires, you lose the right to stay legally — and the UPO won't save you.
- Uploading documents in the wrong format. MOS accepts PDF and JPG under 5 MB. A 15 MB scan or a .HEIC file from your iPhone will be rejected or cause a technical error mid-submission.
- Mismatched accommodation address. The address in the form must match the document you upload as proof. If you've moved since your last permit, update both.
- Paying before getting the reference code. See above — don't do it.
- Not tracking the case. After submission, MOS sends notifications to your registered email. If your inbox filters them as spam, you'll miss a wezwanie — a supplementary document request. You typically have 7 days to respond. Miss it, and the case can be suspended or closed.
Priya, an IT contractor from Chennai, submitted her renewal through MOS in May 2026 — clean file, right documents, paid on time. But the accommodation letter was dated three months before the form and showed a different district than her current flat. A wezwanie arrived. She had 7 days. We drafted a corrected statement, uploaded it within 48 hours, and her case was back on track. The card arrived 11 weeks later. One small mismatch, caught early, cost nothing extra.
Frequently Asked Questions
If I submitted through the old InPol system before April 27, what happens to my case?
InPol cases submitted before 27 April 2026 continue to be processed under the old system — you don't need to re-submit through MOS. If you're unsure whether your old application was registered, check with your voivodeship office directly or contact us. Don't submit a duplicate on MOS; that creates two open cases and significant confusion.
Can I submit through MOS without a Profil Zaufany?
No. A Profil Zaufany, qualified electronic signature, or personal electronic signature is mandatory to sign and submit the MOS form. There is no paper alternative anymore. If you're struggling to set up Profil Zaufany, any Polish post office (Poczta Polska) can verify your identity in person, or many banks offer the verification through their mobile app.
Does the UPO I get from MOS actually let me travel outside Poland?
The UPO confirms your legal stay in Poland while your case is pending. It does not function as a travel document. If you leave Poland while your renewal is pending and try to re-enter without a valid visa or permit, you may face issues at the border. Stay in Poland until your new karta pobytu is in your hands — or consult us before any travel.
How long does a MOS renewal actually take in 2026?
Processing times in 2026 range from 8 to 16 weeks for straightforward cases. Warsaw, the busiest voivodeship, averages 3–5 months even after the MOS switch. Smaller voivodeships like Lublin or Opole tend to be faster. The biometrics appointment — which MOS schedules separately — can itself take 4–8 weeks to arrive in Warsaw. Plan for the longer end.
Can my employer submit the application on my behalf through MOS?
For combined work-and-residence permits, your employer plays a role in the process — they must confirm the job offer and may need to complete separate sections. But the application itself must be signed and submitted by you, the foreigner, using your own Profil Zaufany. An employer cannot submit a karta pobytu application on your behalf. An authorised legal representative (with a formal pełnomocnictwo) can assist — and that's exactly what we do for our clients.
MOS changed the process — it didn't make it simple. If your renewal is coming up and you want a clean file, no wezwania, and someone watching the case from submission to card pickup, that's what we do. Legal Solutions — 98% approval rate. Drop us a WhatsApp — we read every message.
