I'm a USC. My husband is applying for AOE. We got I-130 approved and now he has everything ready to file for AOS, but there is something it's not very clear for us. He has a daughter overseas who's applying along with him for AOS. He included her in his I-485 but we're not sure how to file I-824 for his daughter overseas. Do we include it along with the I-485 package and send it all locally? Or does it have to be sent at a later time to a different location? The I-824 doesn't seem to have much sense to us given the repetition of information. How exactly do the USCIS know how to link that form with the rest of his files if there is no questions about his daughter in that form? Any help on this matter would be greatly appreciated. Thanks.
