well, i mean, you know how if you immigrate to united states through inspection, the only way to change your status is through marriage. i understand that but lets say that parent(out of status one) has a kid that is 7 years old, i know that the kid can change his status too once the parent gets married to a legal resident because after filing the papers the kid is still under 18. but i wonder if it would still be the same if the kid turns 18 right after the marriage. with papers in progress or maybe not. but marriage did happen before his 18th birthday (assuming one day before)
