Well, my immigration people told me the cost for I-140 is 2700 dollars something (with a little increase of the amount). It's not 700 dollars, so that's why I want to wait for a little bit.
-Nonsense! probably they ask you to pay the lawyer fee also.
Read this USCIS website about I-140 filing fee:

8老师，再问一下，如果我现在决定先交140， 过几个月，140还没批，但485排期到了，我可以继续交485吗 （without the new approved 140)？
-Yes.
谢谢！
