First week November received letter in mail inviting us for another interview. Letter says to continue i485 and i130. Knew it was going to be stokes interview. Interview scheduled for dec 4th.
Dec 4th 2020 went to interview. Same officer. Separated us. Took me first and had wife wait in waiting area. Asked a lot of questions. Some questions repeating from first interview. Asked new questions like why did i file taxes as married filing separately, explained reason, asked what things do wife and i have together or have each other listed under. Listed everything from life insurance to costco membership to triple a. Ask if we have joint cell phone and why we dont. And who is on my wifes plan( her best friend since high-school) and a lot of questions like what we do on our off day, wherr does wife work, what is her role at company, what is her schedule. Where she worked prior, who pays what bills and how we both use bank statements etc. Last question was if i paid my wife to marry me. I laughed and said no. Took about 45mins. Then she did the same to my wife. Then later called me in to join and says she believes our marriage is real. Says she will recommend for approval. But we should wait a week, she might need to look through documents again one more time. We went home. 2 hours after interview case updated to we ordered your greencard.
Dec 7th 2020 i485 & i130 changed to approved
Dec 8th 2020. We mailed your card
Dec 9th 2020. Usps picked up your card. Here is tracking number.
Dec 11th 2020. Greencard delivered. Im on vacation right now so haven't seen greencard yet but super excited.
 We probably received a 2nd interview because wife and i work in different states and have apartment ls in 2 different states plus both our ids are different. Plus no joint lease due to wife not being able to be on my lease because of past issues. Plus married filing separately on taxes. If anyone has any questions, let me know. I'll be glad to Answer and help.
