Question about permesso and visa

Hi everyone, I am holding a student visa wich expires in august 23rd, I applied for permesso due to a study that will be started in september 4th. The notification letter showed that the appointment date is september 6th. It is after my visa expiration date. Will I have a problem with this?  Thank you very much!

Generally, if you provide proof that you have enrolled in the same university program and have successfully passed at least one or two of your classes during the prior semester, as well as the other requirements (financial situation, health insurance, rental contract, etc.), you should have no problem.
