sorry, my information in the first answer was not very exact for your case, I reacted to the word "visa" (it was about your "student visa"). The Dublin rule for people with a visa is really that the country which issued this visa is responsible for the asylum procedure during the validity of this visa and 6 months after that. But if you are a student in Germany, you don't only have a visa, you must have a residence permit as a student (normally after §16 or 16b German Aliens Law). Normally people come to Germany with a visa for studing, given in an embassy, and get then a residence permit, mostly for 1 year, from the Ausländerbehörde. In case of a residence permit, though, the Dublin rule is: Germany is responsible for your asylum procedure for 2 more years after the expiring of your last residence permit.
I think it must be difficult to stay so long illegally somewhere, so that after that you have no more problems with Dublin. From our point of view it is not advisable. There are high penalties for staying illegally (at least in Germany) and possibly a criminal case, which can be bad for your perspective.
Perhaps it is easier for you to leave the territory of Dublin Regulation (it is not exactly the same as EU) for at least 3 months (with proof. After that the county which gives you a new visa or through which you manage to come to Europe (in case you have no visa) will be responsible for your case. Practically you need a visa from Norway or coming to Norway as the "first" European country.
