It's Tuesday evening. You filed your karta pobytu (Polish residence permit) application in MOS last week, your old card runs out in a month, and a friend from the dorm just messaged: 'Where's your stamp? No stamp in the passport means you're illegal.' You flip open your passport. Nothing. Your stomach drops. Breathe. Whether your stay is legal while you wait for your karta pobytu depends on when and how you filed, not on ink in a passport. And in 2026 the stamp itself has changed. Here's what is true right now.
So, is your stay actually legal while you wait?
Usually, yes. Polish rules treat your stay as legal from the day you file your temporary residence application until the day the decision becomes final. Official guidance from the Zielona Linia (gov.pl) says this applies whether the final decision turns out positive or negative. The protection has conditions, though. You must have filed while your previous stay was still legal, and your application must have no formal defects, or you must fix them on time.

So the real checklist is short:
- You filed before your previous visa, permit or legal stay expired. A day late changes everything, so count your dates carefully.
- Your application was complete, or you supplied any missing documents inside the deadline the office gave you.
- You filed the right way. Since 27 April 2026 that means electronically, through the MOS portal.
Where did the passport stamp go? What changed on 27 April 2026
For years, the voivode (the regional office, urząd wojewódzki) pressed a stamp into your passport to confirm your application. That stopped. From 27 April 2026, applications for temporary residence go through the new MOS portal, and the office no longer stamps passports. Instead it issues a zaświadczenie (a certificate confirming your application) that you download from the system. The Lower Silesian voivodeship office explains the switch on its official MOS news page.
The order of events matters, because people panic in the gap:
- You submit the application in MOS. The system gives you a UPO, an official confirmation that your file was received.
- An officer checks your application for formal defects.
- Once the application is verified, the certificate appears in your MOS case.
The UPO is not the certificate. If you have the UPO but no certificate yet, your file is probably waiting in the queue, not rejected. Official training material prepared for the offices also says that missing fingerprints should not block the certificate, but offices may be slow to issue it. If a week or two passes with nothing, ask for a status check instead of waiting in silence.

What does the certificate let you do, and what doesn't it?
Think of the certificate as proof of one thing: you have a pending application and your stay is covered. That's valuable. It is not a magic key.
- It does show that your stay in Poland is legal while the case is open.
- It does not replace your visa or your karta pobytu. Training material for the offices says plainly that it is not a travel document.
- It does not, by itself, create a right to work. Guidance from Zielona Linia stresses that legal stay and the right to work are two separate questions.
On work: whether you can keep working while the application is pending depends on what your current basis for work is and whether your employer, job and conditions stay the same. Don't change employer, position or pay during the wait without checking first. Ask HR what paperwork they hold, and send us the documents if you're unsure.
On travel: the old stamp already let you leave Poland but did not guarantee you could come back, and it did not entitle you to travel through other Schengen countries, according to the Wielkopolska voivodeship guidance for foreigners. A certificate that is not a travel document is no safer. Do not book a flight home until you've confirmed your exact situation. Our post on trips outside Poland and your 5-year count explains how absences can hurt you later.
Practical tip: the day the certificate appears in MOS, download the PDF, save it on your phone, email it to yourself and print two copies. Employers, landlords and officers ask for paper, and a MOS login that won't load at the wrong moment is a bad time to find out.
An illustrative example: Bikash, a welder from Pokhara, filed three weeks before his card expired and then heard from a coworker that 'no stamp means illegal.' He nearly quit his shift to wait at the office. A quick check showed he had filed in time, with a complete file, and his certificate was simply not yet issued. He kept working under the same conditions, and the certificate appeared a few days later. (Composite story, details generalised.)
What if your documents are incomplete or your permit expires before the decision?
If the office finds a formal defect, it tells you what to add and gives you a deadline. Treat that deadline as the most important date in your life that month. The protection for your stay depends on defects being fixed on time, so don't let a notification sit unread in MOS.
If you filed after your previous stay had already ended, the situation is different, and the usual 'legal while pending' logic may not protect you. Don't wait and hope. Message us the same day with your dates and we'll tell you honestly where you stand.
Lost your job in the middle of the process? The notification and job-search clocks run separately. Read what to do after losing your job on a karta pobytu before you sign anything. And if you're wondering how long the whole wait should last, see how long a foreign employee's karta pobytu takes in 2026.
Your checklist while you wait
- Write down three dates: when your old permit or stay ends, when you filed, and any deadline from the office.
- Log in to MOS at least twice a week. Missing a request for documents is the easiest way to damage a good case.
- Download the UPO the moment you file. Download the certificate the moment it appears.
- Keep working only on the terms your current basis for work allows. Ask before changing employer, job title or pay.
- Do not leave Poland until you've confirmed you can come back safely.
- Keep your health insurance and your address up to date. A decision letter sent to an old address costs you time you may not have.
- If anything looks wrong, message us before you act, not after.
