One has to register within the first three months of stay in Germany for Resident Permit.  A residence permit issued to students is valid for maximum two years. It needs to be renewed if the duration of the course is longer than the stated two years.It can take a long time to be issued, which is anywhere between eight to 12 weeks. Since this means two to three months, international students are advised to apply as soon as possible.
