All the best. I just got to the end myself..
Initially I had just Affidavits, pictures, social media post and comments, emails sent back and forth,boarding tickets, pass and stamps
Marriage certificate..chats records that had dates with our pictures in the screenshots, money receipt...
I only had this with need documentation when I filed my 1-30 in July of 2019..
Never got RFE
then had more proofs during my husband's interview...
Honesty is key here..FYI there was no red flag as others call it in my case
