Sponsoring a student to extend the visa

I do not think it is possible - at least I never heard of it.

Which part of the student visa requirements do yoiu want to circumvent by having this sponsorship?

Not how it works. There is no "sponsorship" for any kind of visa. One on a study visa needs to put (currently) 11,207 euros a year in a German blocked bank account to cover living expenses. One can theoretically get around this if a close relative (NOT a friend!) who is residing in Germany would sign a legal document talking full financial responsibility for you. But this is a crazy solution because they would have unlimited liability! That a friend or even a relative not in Germany can somehow do this is just not allowed. They could easier just give or lend you the money with no further risk.

And the other factor of continuing to study is to be academically eligible and actually in a program. Not possible if one has dropped out, already finished or been thrown out.

    Hi
I am student at Germany. My visa is going to expire and I have extend it. Is it possible that an EU blue card holder( my friend) could sponsor me to extend it?

Your friend could enter into a Verpflichtungserklärung for you if he earns enough to cover both his and your living expenses and if his BlueCard is valid beyond the validity of the visa you are applying for.

Thank you

@ALKB  only a close relative residing in Germany can usually do this. Otherwise they can't count on getting having all liabilities covered without excuses. And for the same reason relatives in another country can't usually do it either. I don't know if this is stated officially anywhere since most of the government sites that mention the possibility of a Verpflichtungserklärung don't go into any specific detail about it. I know the subject came up years ago on this site. Possibly it is an interpretation made by specific officials in some cases that might not be binding in all cases. But one should anyway not assume it is so easy. If one has people willing to put up the money, then they should just transfer it to the needed blocked account. Why in the world would they take on unlimited liability by signing such a thing?!

Oh, it´s not easy, but my parents have successfully sponsored people who were not related to them whatsoever and for visas that were not just tourist visas.

It´s not something I would advise anybody to do, it´s a tremendous financial risk.

Also, somebody who is not a permanent resident will be questioned as to why they would want to take on this responsibility.
