綠卡申請人地址一問？

Current, I like to DIY NW. One practical question is

1) Now I live in an apartment and this address is temporal and I may move out
in near future. Do I need to find a friend in same city who has permenant
address and use his address?

2) if I use friend's permenant address, it means my current address has
changed. This is not true and will cause any problems?

2) If I use my own current temporal address and use this address when applying
, after I move out, I use the form to inform USCIS the address change. Can
USCIS connect new address to my petition?

How do you handle this question?

Thanks a lot.
