謝謝老師！
還想再確認一下避免搞砸：
這樣的interfiling就是說完全不提交新的485申請，就直接寫信要求轉原來的我老公case裏邊的兩個485？
-Correct. This is the law allows you to save the money and USCIS energy and time. Thus, USCIS does not need to process your I-485 all over again.
還是說在正常的485表格、申請費之外，再額外的附上這個interfiling的petition letter？
-No.
那麽要填的表格和交的費用就都是一樣，
但是如果transfer成功的話，後麵就不會再要我們打指紋了？
-Do nothing. It is equal to your filing two I-485s already. Your pending I-485 will be considered for approval based on both of your I-140, depends on which I-140 PD is current.
你給的那個鏈接裏的情形，因為是他自己的兩個不同case之間轉485，所以他好像沒有重新提交表格這些，直接就是寫信要求把原有的485轉到另一個剛批好的I140上麵。我們的情況要複雜一些，所以還是有些不明白。
-I just give you an example and the principle is the same for all cases, even can transfer I-485 from I-130 (family based) to I-140 (employment based).
謝謝指教！
