Should I Update Address? K1 visa

[Kwilso25 1]

Hello everyone 2 quick questions. Nov. 2021 filer for I-129f waiting for our approval which I will assume will be sometime in January 2023. I am currently living in Lima with my fiancé as she is 6 months pregnant with our daughter. Actually it’s pretty funny she might be born when we finally get approved fingers crossed. 

Question 1 : I recently changed my address to my brothers address in San Diego as I will be staying here in Peru until we go back to US as a family, but when I changed it I changed both physical and mailing address to his San Diego address. Should I change the physical address back to my Los Angeles address that is on my license and all my documents? I just don’t want any problems further down the line in this process. Does my physical address really matter? 
 

Question 2: I don’t remember what mailing address we put down for her in the application but we are now living in a new apartment and will have this address until we leave. Is there a way to update her address to our new address here in Peru? Does it matter or is it irrelevant because I read that anything after the actual application is sent and done online and through email. I just want to make sure because I do remember filing in her address. Thank you everyone!
