請教8老師，我是2年綠卡現在想申請成年兒子移民，他現21歲半持F1在美國念大學，請問，第一步提交一個i-130表，還提交G-325表嗎？-No.
還需要未婚證明嗎？-No.
經濟擔保表是和485一起提交嗎？-Yes, but he cannot submit I-485 until the PD is current a few years later.
他在美國申請不會影響他的F1簽證嗎？-If he leaves US, it probably will affect his F-1 visa application, but if he just do the F-1 transfer from one school to another or study in a graduate program within US, it should not be affected because such F-1 transfer or graduate study does not need USCIS approval.
我是新人一頭霧水，希望老師和過來人給個材料清單，
-Nothing special. Just file I-130 only following the I-130 instructions at present.
萬分感謝！
