Hey! Nice to meet someone who also has an upcoming interview at Newark. I haven't received any confirmation yet if it will be a combo interview but I've read in most cases if you have a pending I751, it ends up being a combo interview so I'm taking my spouse with me. Have you heard of people receiving a confirmation on whether or not it will be a combo interview?
I had also submitted a lot of on-going relationship evidence but I feel like with USCIS its never enough so I am planning to take at least the following:
Appointment letter
I751 Extension Letter
Mine:
Green Card (2-year)
Driver license + Real ID
Passports
Birth Certificate
EAD Card
SSN
US Citizen Spouse's passport
US Citizen Spouse's driver's license
US Citizen Spouse's Birth Certificate
US Citizen's OCI (This is an Indian thing)
Tax Transcripts (last 3 years)
Tax Returns (last 3 years)
Marriage Certificate Original
Property Deed
Bank Statements:
Driver's License showing same address for me and spouse (copy)
Proofs of Bonafide relationship:
Pictures of all trips with family (last 2 years)
Flight tickets, hotel reservations
Beneficiary proof in life insurance policies, 401ks, etc
I know a lot of it is overkill but better be prepared than delay being done with USCIS. Are you taking SS-5 for name change? Can you think of anything else I should take or does this list look good? I will let you know about my interview experience once done.
