8老师：你好! 很抱歉，我发错信息了，是今年6月收到NVC转F1的信。而不是F3。现在要F1转F3。请问如果沿用原来的case的基础上转F3，我应该怎样做?
-Just write a letter to ask USCIS to upgrade your I-130 from F1 to F3 (provide the copies of I-130 approval notice, your child birth certificate, and her marriage certiticate).
需要重新缴费吗？
-No.
需要重新填写I-130 表吗？
-No.
优先日期应该如何计算？
-It is the same as before. By the way, as I mentioned to you before, if your child got married before you became the US citizen, then the I-130 (F2B) has been void, so any upgrading of the I-130 will be invalid (USCIS will find it sooner or later).
谢谢！
