Pjiang大侠和8老师, please help for address question

My son is a college student. I submitted i485 for him using our home address. I have just got his receipt. Now he is back to college. Should I need change his address to his college’s address so that he can get his fingerprint in his college area? Otherwise, I am worried that his fingerprint will be scheduled in our home area. That is difficult for him during the school time as he has to fly back home.

If I change his address now, is there any problem with it?

Any other suggestion is highly welcomed.

Thank you in advance for your help
