请教8老师
给父母一起在美国国内申请绿卡，是两份petitions. I-864 Page 2, Part 3 (Information about the Immigrants You are Sponsoring).
# 2: You are sponsoring the following family members of immigrants at the same time with the principle immigrant named in Part 2 (do not include any relatives listed on a separate visa petition).
我有点疑惑， 父母是一起递交，但是两份分开的申请。不知道该怎么填准确。多谢了!
