Adjustment of Status - I-485

Hello everyone.
I'm an overstayed F1 visa holder since 2014.
I got married May 2017 and lived since then with my wife.
We have a beautiful daughter now.
We applied for Aos after our baby, i130, I 485, l765 ..... all together
Until now everything is alright and following the processing time as we received
Our interview after 4months of application.
I have 4 concerns about our case.

1- my wife at a certain time of her pregnancy, applied for food stamp and Medicaid!
The papers for that show clearly that she didn't take it for me ....
IS THIS GOING TO CAUSE TROUBLE AT THE INTERVIEW WITH USCIS?

2- MY wife doesn't have a good credit and have not worked much in her life yet (21 yo) .
I have no social yet
SO WE HAVE NO :
-joint account
- no joint bill-
-No insurance
WE ONLY HAVE A MONTH TO MONTH HOUSE LEASE MADE BY THE LANDLORD OF THE PLACES
WE OCCUPIED SINCE WE GOT MARRIED.

3- TODAY I DISCOVERED THAT MY LANDLORD LET HIS SISTER US OUR ADDRESS TO APPLY FOR THE SAME TYPE
GREEN CARD. FAMILY BASE.

I WAS CHOCKED . MY WIFE CRIED ALL DAY AFTER I TOLD HER. SHE WAS SAYING THAT IT WILL CLEARLY
PUT US IN TROUBLE.

I DON'T KNOW WHAT TO EXPECT. I NEED YOUR ADVICE PLEASE.

INTERVIEW IN 1 MONTH
