No Traditional Address for Pre-Interview Items

[Chiriqui Champion 0]

Okay, I am getting married to my Panamanian fiancee in June and am in the process of getting all the paperwork filled out for the I-130 for her and her two girls. The I-130 asks for their current address and form g-325a asks for their address history for the last five years. The problem with where she lives in Panama is that there are no official street addresses (i.e. 123 Maple Lane). The bills she gets at her apartment all have a different address listed and are hand delivered by the utility company they have the general area, such as her neighborhood and what landmarks her apartment is between, but do not list her mailing address. There is a general post office where she lives, but citizens have to go there and ask for their mail. I have tried a few times to send her letters but she has gone to the post office and never received them. What am I to do? I am worried when I submit my I-130 and g-325a that she will not receive the forms she needs from UCIS.
