A quick email to firstname.lastname@example.org will tell you of this fact.
If you want to chance a particular traffic cop knowing Article 94 of the Act on Road Transport, that's up to you. Personally I keep a photocopy of the page of my passport with my most recent entry stamp on it. Much quicker than going down to the station and waiting while they check it, find you're right and then apologise. (Of course it is always possible to avoid that trip by paying a 'fine' for not having the correct documentation).
This simply not true as I have one after being here for seven years :O)
And harry I don't know where you get your info from but it is very bad advice and I suggest you get your facts right before posting :O)
I've said it before and I'll say it again: it is impossible for an EU citizen to obtain a permanent residency card in Poland. While the travel site you quote is no doubt very useful for booking a hotel, I prefer to get my information from slightly better sources. In this case we are talking about foreigners in Poland so the definitive source would be the Urząd do Spraw Cudzoziemców, the Foreigners Office. Checking their website brings this page: udsc.gov.pl/files/old_file/44ffd8816f947_UdSRiC_91_2006_pl_ en.doc.
The information about permanent residence starts on page six of that document. I quote "The Union citizen who obtained the right of permanent residence is given a document certifying the permanent residence right based on the application of Union citizen." Note the word document
. Could that be the same as a card
? No. Again I quote "A family member who is not a Union citizen, and that obtained the right of permanent residence, shall be provided, on his/her request, with a permanent residence card of a family member of a Union citizen." So, as I said before: it is impossible for an EU citizen to obtain a permanent residency card in Poland.
I see exactly where you get your info from and it is clearly wrong. I suggest you get information from better sources so that you avoid getting facts wrong when posting.
Hope you enjoyed the education.
