This is the list from my cover letter:
Documents for Petition:
Application fee of $750 with Form G-1450 (Credit Card Authorization).
Completed Form G-1145 (E-Notification).
Completed and signed Form I-751.
Copy of Permanent Resident Card (front and back).
Copy of our marriage certificate.
Copies of passports for petitioner and spouse.
Evidence of Bona Fide Relationship:
Driver's licenses showing shared residence.
Tax returns for 2022 and filed jointly for 2023. The petitioner had no income after becoming a lawful resident in 2022 and her identity was not yet established so tax return in 2022 was filed separately.
Joint bank account and back transaction records.
Spouse’s credit card summary showing petitioner as an authorized user.
Two affidavits of support.
Joint apartment lease agreement.
Copies of offer letter and student ID from the University of XXXX.
Faculty/Staff IDs and offer letters from XXXX for both of us.
Life insurance policies naming each other as beneficiaries.
Spouse’s health insurance listing petitioner as a dependent.
Joint AEP electric bill. Columbia Gas and Spectrum Internet bills showing our names and the same address.
Photos with family, friends, coworkers, and shared activities.
Cards from family and friends.
After I sent the package, I noticed some people talked about a notice enclosed in the 2-year green card envelope. It says, "Use this tear-off portion to speed your application for an extension or replacement card."
But it was too late for me to include the notice in the package so I uploaded the scanned copy to the document section after my case was added to my online account.
I'm not sure if that helped but make sure to include the notice if you're about to file your i-751.
Let me know if you have any questions!
