问贴。婚姻绿卡之2转10年生物采集费。

请问美国公民配偶需要在一开始就提交85刀生物采集费吗？还是先交595刀申请费，生物采集费之后需要才交？我看别人的申请贴有交，官网的计算器也包括这费用了。到我看这段话好像又不用。求经验分享。
Biometric Services Fee.
1. Conditional Resident. Each conditional resident and conditional resident dependent included in the principal
petitioner’s Form I-751 is required to submit a biometric services fee with this petition, in addition to the required
filing fee. (See the What Is the Filing Fee section of these Instructions.)
2. U.S. Citizen or Lawful Permanent Resident Spouse. If you are the U.S. citizen or lawful permanent resident
spouse, you do not need to include a biometric services fee at the time this petition is submitted. If USCIS later
notifies you that you must submit your biometrics, you will receive a biometric services appointment notice with
instructions on how to submit the additional fee.

这段第二条不用交费说的是和你共同申请的你的配偶（公民或者绿卡持有者）不需要交指纹采集费，不是主申请人。所以还是要交的。
