请教一下近期给父母办过绿卡指纹的mm们，$85是打指纹的时候现场交，还是寄I-130/I-485的时候就包括进去？

需要每个form每人写一个check吗？还是总数写一个check就行了？比如一个总额 $3520的check，还是要分开写？如果分开的话，要分多细？

option 1

6 checks: 2 checks of $535 for each I-130, 2 checks of $85 for each biometric screening, 2 checks of $1140 for each I-485

option 2

3 checks: 1 check of $1070 for both I-130s, 1 check of $170 for both biometric screening, 1 check of $2280 for both I-485s

先谢谢大家了！
