Harry, can you explain this one?
I meant that it is possible to get a residency permit here without being an EU citizen and without working or studying: I know people who have done it. The problem is that the whole thing is a very severe pain in the arse.
Yes, I suppose a museum would have no interest in someone working for free with a degree in their subject matters giving English tours ...
They would have zero interest in you working for them full-time as a non-EU citizen. The days of 'Hi, I'm a native speaker of English; give me your finest job' finished in the mid 1990s. There's no shortage of EU citizens who have history degrees and speak fluent English.
I am asking this, because I recently was at Długa 5 (hadn't been there for ages, the EU section completely deserted, you might have thought all EU citizens have left Warsaw :) )
Anyway, one of the staff there told that there was a plan to replace that piece of paper with a proper plastic one, not unlike a Polish ID.
I was there last month to collect my 'confirmation of right to reside' (because clearly an EU passport isn't enough to prove one has the right to reside in Poland) and asked about photo ID: they said nothing is available and that nothing will be being made available any time soon.
To give the OP some idea about the amount of red tape in Poland (as he clearly has no idea): my car registration recent expired (Poles can register their cars for an unlimited time, foreigners cannot). I own my car, I own my flat, I live entirely within Polish law and I pay lots of tax in Poland. In order to do something as simple as updating my car registration (no details at all had changed), I have so far needed to visit six separate places (a total of seven times, as one place required two visits and in another office the clerk point blank refused to do what the poster on the wall in his office said he would do) to get various bits of paper stamped and have waited six weeks so far; I still need to make one more visit to the car registration office in two weeks' time to collect another stamp. Oh, and the police came to visit me twice to check I live where I live (I wasn't home either time so on the second visit they went downstairs and spoke to the nice old lady who lives below me and asked if she could confirm that I live in the flat which I own and where I am registered as living). You might want to note that the process was simpler and faster because I'm an EU citizen.
