NIW at NSC need hlp for 485

No RFE required. Only I140. Exactly 16 month. The approval notice is still on the way.

One question.
I submitted NIW using my current address (A1). I am going to change my home address (A2) in the next month for my family. And in August, I will start a new job so I will have the new address (A3) and my family will stay at A2 for a while. My questions are

1. Is it required to submit I485 using A1? I may not have enough time to finish the physical exam.
2. Can I always use A2 for my address to contact with the USCIS?

Thank you very much.
