@Theano Delgado Pictures, put them in a word document and title them saying where they were taken and names of people in them then print in A4 papers. You need significant evidence like joint taxes, joint leases, joint health, dental, vision, life, renters insurance, travel together, affidavit from family and friends, 401k beneficiary, joint bank accounts, joint credit cards. All evidence from the day your conditional greencard was approved.

thank you
