removing conditions for stepchild over 18 in US filing separate from parent

[dm559 34]

Hi everyone, I hope someone can give me a little info, web search hasn't yielded much on my topic. My wife, stepdaughter and stepson are now in the US, my wife and stepdaughter have been here 9 months now and they have a 10 year green card. My stepson has been in the US almost 3 years and his temporary residency is about to expire so we're about to file his I-751. Both of my stepchildren are now over the age of 18 and I've legally adopted both of them (no immigration benefit) and they both now have US birth certificates but they are not US citizens.

My question is this: with my stepson's application do we need to submit proof of marriage between my wife and I (stepson never married) and proof of ongoing marriage or since his immigration is independent (although he derived immigration status due to my marriage, USCIS initially said that their immigration are independent of each other because they didn't file their immigration petition at the same time) Thank you in advance.

Did you legally adopt them before age 18? Did they have green cards before age 18? Were they living with you before afe 18?

The marriage took place before they were 18, green cards after 18 but before 21. Adoption has no immigration benefit, it was a family decision and took place after the age of 18. Their immigration is under their adoptive names. My wife and stepdaughter has 10 year green cards because their immigration was finally processed by the time our 2 year marriage mark, my stepson was given 2 year only because his immigration was processed before the 2 year marriage anniversary. We all lived together before the children were 18 and they still reside at home while in college and working. My son's temporary residency expires in a few months and so he is the only one that has conditions to be removed.
