How to get rid of my german citizenship?!?!?

You can formally renounce your German citizenship at the German consulate in your "other" country of citizenship, which you do not mention. I'm not sure why anybody would want to give up being a citizen of Germany or any country that allows him to live freely in any of the 14 EU countries, so I assume you are a citizen of another EU country already. But even then it would make no sense. There's no disadvantage, no additional tax burden, to be a citizen of Europe's most powerful nation, so I'm confused. A student visa is a non-immigrant visa, always, with the sole exception of France, where the time as a student is counted toward residency, once a diploma from a French university has been obtained. In all other cases, you could spend hundreds of thousands of dollars and a decade as a student and it would not have any influence in obtaining residency to such country. I don't grasp what renunciation of German citizenship and studying in another country have to do with one another.

You will not get citizenship of any country by studying and as it is a non immigration visa you can't remain in the country and work, you have to return home....... nor can you 'give up' citizenship as then you are classed as 'stateless' ......... with German citizenship the whole of the European Union is your work place without changing or getting anything

Student visas are temporary NON-immigration class of visas issued on the condition that students return to their country of citizenship immediately upon completion or termination of studies. IF you could ever qualify for immigration to either country, you would have to obtain legal permanent residency status through some qualification other than student. (PR status in Canada, green card in US.) None of the time you spend in a country as a student counts toward residency requirements for eventual application for naturalization.

If you qualify for any other citizenship and naturalize as e.g. Canadian you will automatically lose German citizenship. The only way to prevent that is getting a Beibehaltungsgenehmigung von der deutschen Regierung. The real question is whether you ever will be eligible to apply for Canadian citizenship. Just studying there won't do it.

No. You can not renounce your German citizenship until you obtain citizenship in another country. Merely attending university in Canada or the US does not grant you any rights to live in the country after your study permit end... let alone any type of citizenship. In addition, it is going to cost $150,000+ for a typical university degree in Canada or the US. In Canada, if you graduate from certain university programs you can apply for a post graduate work permit. If you then find a skilled job offer in your field and work there for one year, you may then apply for permanent residency. Only a limited number of applicants are selected each year and you must pass background, medical, and financial checks. After getting permanent residency status you must then live in Canada as a permanent resident for at least three years to apply for citizenship. In the US, if you graduate with certain college degrees you can apply for a green card. Only a limited number are given out and you have background, medical, and financial checks. If you are selected, you must then live in the US as a green card holder for several years before you can apply for citizenship. I have no idea why you want give up your German citizenship. However, you can't unless you (somehow) qualify for citizenship in another country -- a process which will could take a decade or more.
