I have some questions on the working permits issued for EU/only limited to one country:
First, if a non-EU-citizen (Turkish) receives a job offer for an EU-country (in this case: Poland), are they usually issuing a EU working permit limited to one year and to this specific job? Other websites told me there is also country-limited working permits, so i'm wondering what is the standard procedure.
Second, assuming the one year EU working permit is issued, then after 12 months (at least this is the case for Germany), it can be extended to an unlimited permit (tho still limited to the specific job?). So what happens, if at some point after the first year, the person would receive a job offer from another EU-conutry (in this case hopefully Germany

Third, assuming the permit is limited to Poland, can it become EU-wide under certain conditions?
I hope someone can help me with this, as I've been fishing in the huge sea called internet, yet only found very few and vague information.
Thank you a lot in advance
