回复：请问8老师，叩谢了

合并在提交485 后4个月，180天未到时发生。

现要求交I-140 AMEND，

-Because you filed your I-485 before the company combination, it is not necessary to file the I-140 amendment. Of course, the I-140 amendment filing is fine and at least it does not affect your I-485 anything.

 会不会影响485审批，

-No.

这种批准要多久， 是不是相当I140重新来一遍的时间

担心很长时间，排期回来后，I-140 AMEND 还未批准，绿卡名额没了。

-Your I-485 will be approved based on your old approved I-140 unless USCIS make a decision before your I-485 pennding is > 180 days (it seems impossible to happen due to visa number unavailable). So, don't worry.
