A change of address during residence permit proceedings — how to notify the authority and why it decides the case
Moving house during proceedings is one of the most common reasons why an application for a residence permit ends up being left unexamined. The provision is short and unforgiving: if you do not notify the authority of a change of address, service at the previous address has legal effect.
The provision that decides the fate of the application
Art. 41 § 1 of the Code of Administrative Procedure: in the course of proceedings, parties and their representatives and authorised representatives have a duty to notify the public administration authority of every change of their address.
Art. 41 § 2: where the duty specified in § 1 is neglected, service of a letter at the previous address has legal effect.
The practical meaning is this: the risk of not collecting a letter rests with the party, not with the office. A letter sent to the last address known to the authority produces full procedural effects, even if the addressee never saw it. The duty lasts throughout the proceedings — from their initiation until their conclusion.
How one move turns into a lost case
The chain of events is always the same, and each link rests on a different provision. It is worth knowing it in full, because it can only be broken at the beginning.
The request to remedy formal defects
If an application does not meet the requirements laid down in the law, the authority calls upon the applicant to remedy the defects within a set period of no less than seven days, with an instruction that failure to remedy them will result in the application being left unexamined (art. 64 § 2 k.p.a.). In residence matters such a request is the rule, not the exception.
The fiction of service
Where an item cannot be served, a notice of the possibility of collecting the letter within seven days is left in the letterbox or on the door and, if the item is not collected, a repeat notice within no more than fourteen days of the first one. Once that period has passed, service is deemed to have been effected and the letter is placed in the case file (art. 44 k.p.a.). The period set in the summons then runs as if the letter had been collected.
Leaving the application unexamined
Failure to remedy the defects within the time limit ends with the application being left unexamined. This is neither a decision nor an order, but a material-technical act of which the authority notifies the applicant in writing. That is why neither an appeal nor a complaint lies against it.
The effect on the legality of the stay
Art. 108 ustawy o cudzoziemcach makes protection of the stay conditional on the application containing no formal defects or on the defects being remedied within the time limit. In that case the voivode places a stamp in the travel document and the stay is deemed legal from the day the application was submitted until the day the decision becomes final. Leaving the application unexamined means that this condition was not met.
How to notify a change of address effectively
The method depends on the form in which your proceedings are being conducted. The principle, however, is the same: the notification must reach the file of the specific case, and you must have proof that you filed it.
Cases conducted electronically — since 27 April 2026
Since 27 April 2026, applications for a temporary residence permit, a permanent residence permit and an EU long-term resident's permit are submitted exclusively electronically in the MOS portal (Moduł Obsługi Spraw) (art. 225a ust. 1 ustawy o cudzoziemcach), and offices conduct proceedings initiated by that route in electronic form.
The key address then ceases to be the postal address and becomes the electronic delivery address. The Mazovian Voivodeship Office (Mazowiecki Urząd Wojewódzki) indicates that an e-Delivery (e-Doręczenia) mailbox is needed to receive summonses, information about the date of attendance for fingerprinting and information about the date for collecting the residence card, and that thanks to it correspondence will reach the addressee even after a change of place of residence or a trip abroad.
The same office states a housekeeping rule: the subject line of the item should contain the case number and the foreigner's first name and surname, and one electronic letter concerns one case. Send a notification of a change of address according to the same rule — as a separate letter to the specific case.
Cases initiated earlier and other correspondence
In proceedings conducted on paper, the notification is filed to the case file at the voivodeship office conducting it. Confirm the form and the channel with that office — the way it is organised varies, and it determines whether the letter reaches the right file.
Whatever the channel, take care of three things: the letter must state the case number, it must indicate the old and the new address, and you must have proof that you filed it. Treat entering the address in the application handling portal as an additional step, not as a substitute for the notification — there is no settled case law establishing that an entry in the portal alone satisfies the duty under art. 41 § 1 k.p.a.
If an authorised representative is acting in the case, the duty under art. 41 § 1 also covers their address.
The summons from the office never arrived — what can be done
First establish the facts: which address the letter was sent to, when it was posted and whether the file contains proof of service or a returned envelope with annotations. Without that it is impossible to assess whether the time limit began to run at all. A party has the right to inspect the file of their own case.
If the deadline was missed through no fault of the party, an application to restore the time limit under art. 58 k.p.a. is available. The time limit is restored at the request of the person concerned if they show it to be plausible that the failure occurred through no fault of their own. The request must be filed within seven days of the day on which the cause of the failure ceased and, at the same time, the act for which the time limit was set must be performed — that is, the missing documents must be filed together with the request.
If the authority left the application unexamined even though there was no basis for doing so, the line of defence is a request to expedite under art. 37 k.p.a., followed by a complaint about the failure to act. The Supreme Administrative Court (Naczelny Sąd Administracyjny), in a resolution of a panel of seven judges of 3 September 2013, sygn. I OPS 2/13, held that a complaint about the authority's failure to act lies against leaving an application unexamined (art. 64 § 2 k.p.a.), pursuant to art. 3 § 2 pkt 8 Prawa o postępowaniu przed sądami administracyjnymi.
In parallel, consider submitting a new, complete application. Leaving an application unexamined does not as a rule deprive you of the right to apply again — provided that the substantive-law deadline has not expired. In residence matters that reservation decides everything, because an application for a temporary residence permit is submitted no later than on the last day of legal stay.
Before the voivode and the Head of the Office for Foreigners (Szef Urzędu do Spraw Cudzoziemców), any natural person with capacity to perform legal acts may act as an authorised representative (art. 33 § 1 k.p.a.). Before a provincial administrative court (wojewódzki sąd administracyjny), only an adwokat or radca prawny (Polish regulated legal professions) may act as an authorised representative; at that stage we can prepare the pleading, which the party signs and files themselves.
The most common mistakes
Relying on an SMS. An SMS notification tells you that a letter has been issued — it does not replace service and does not say which address the letter was sent to.
Reporting the change of address only to the employer or only in the portal, without a letter to the case file.
Registering your residence instead of notifying the authority. Changing data in another register is not a notification to the authority conducting the proceedings.
Delaying after returning from a trip. The seven-day time limit under art. 58 § 2 k.p.a. runs from the moment the cause of the failure ceased, not from the day someone decided to deal with it.
Having no active e-Delivery mailbox in a case conducted electronically.
Editorial team — stage 2 (substantive review). The provisions have been checked against the texts of the statutes and the case law in the Central Database of Administrative Court Rulings.
What this means for you
- File the notification of a change of address as a separate letter to the file of the specific case, with the case number and proof of filing — do not rely solely on an entry in the portal or on information passed to your employer.
- If your case is being conducted electronically, the address that counts is the electronic delivery address. Set up and activate the mailbox before submitting the application and check it regularly.
- When you realise that a summons never reached you, act within seven days and file the missing documents together with the request to restore the time limit.
- Before you treat the case as lost, check in the file whether the office has proof of service. Its absence changes the assessment of the entire proceedings.
