confused about 3 months residency is required for N400

[minglevi 0]

Family member is going to file N400 

Her 5 year anniversary date is Dec. 7 2018 so she can file as early as 09/08/2018

 

But am confused about from where she can file...

Currently she is Seattle WA but she might move to New jersey in or around sept. 2018  and she might be in NJ when she file N400

 

so she needs to prove that she was residing in NJ for at the time of filing?

what type of documents does she need to prove that?

Most likely a utility bill or bank statement or her new driver’s license.

Post office acknowledgement of change of address will not work?
