To continue living and working in any country, particularly in Europe

Thank you for your statement.

If you have specific questions about movig to, living or finding work in Germany, you may come back and post them here. We are always happy to help!

I prefer to be permanent resident and finding work in Germany... Can you please help me and guide me step by step? What are the requirements? And how much cost should be prepared?... thanks.

You have come to the right forum, which already contains lots of information and good advice on these topics.

Please read and follow as much of it as applicable. If you then still have detailed questions, which were not addressed yet, you are welcome to come back and post them here.

(But, sorry, a "step by step" guide is not available, as the topic is too broad and the range of individual cases too diverse for that. Success is, as usual, with the resourceful ones - so please put it together by yourself piece by piece!)

And these are some false expectations to begin with. One must first line up work with an employer willing to take the extra effort, risk and cost of recruiting you as a non-EU person so that you can get the work visa. This will mean having highly demanded skills strongly correlated to having university degree(s) and experience. And for the vast majority of jobs, having a high level of German.  Low- or no-skilled workers have no chance. Non-German speakers will only find work in very selective fields and even then usually have a competitive disadvantage over workers who do know the language. One usually needs English in addition, not as an alternative to German. And then if successful, one gets temporary residency. Usually after 3 years one can get unlimited residency, never from the start, NOT how it works.
