Filling N-400

[Gussan]

For filling form N-400 can we put P.O.Box address for mailing address or it's not allowed.

It's not allowed, sorry. Please see the Form N-400 instructions, Part 4. Item A. (Information About You).

If I were in your place, I would use the physical address where I actually reside. Why would I take the chance, it's not worth it.

Gussan, part 4 B is specifically for P.O. Box address (Mailing Address).

Rough Neighbor, you have to understand that some addresses have no mail delivery and residents are assigned P.O. Box where they pick up their mail. So the reply from USCIS addressed to physical address will not be delivered.

No contest.
