I hold a Germany student residence permit (Aufenthaltstitel- I’m a Non-EU citizen) and if I leave Germany more than 6 months my visa will be invalid. My situation is that I am in Hungary for my exchange program internship (I got a Hungarian residence permit for that) and after a period of 6 months, the company and I would like to extend my internship for another 6 months. So I want to ask that, is there a certificate (fiktionsbescheinigung) to grant permission for student like me to extend my stay in another Europe country? Or can I return to Germany for 1-2 months and come back to Hungary to continue my internship to keep my student visa valid?
P/s: To be more clear, I still enrolled in my university the whole internship period. I still have my health insurance and I have my dormitory sublet to another student with approval from the university
I really don’t want to give up on this opportunity to continue the internship so I’m very appreciated if you have some idea to help me with this.
