Not sure if this is the right forum for this question. Asking for my friend, he is within the 90 day window to apply to get the conditions removed from his green card. He came here on a spouse visa and got a conditional green card. They are in the process of getting a divorce, but the divorce papers won’t be finalized by the time he needs to submit his papers to uscis.
Does he have to apply jointly with his wife? Or can he still file separately even though he doesn’t have divorce proof yet?
