part 3 #9 asks me to fill in
"I am sponsoring the following family members immigrating at the same time or within six months of the principal immigrant named in Part 2 above. Do not include any relative listed on a separate visa petition"
我同时为我父母递交I 130 visa petition, 所以我会为父母每人填一个I864，我应该怎么填这个问题呢？比如说，在给我父亲的864上，我要不要在这个问题上写我母亲呢？我母亲满足“I am sponsoring the following family members immigrating at the same time or within six months of the principal immigrant named in Part 2 above”但是不满足"Do not include any relative listed on a separate visa petition" 因为我给我妈也交了visa petition 啊。
同样的，part5 about household size, should I count both my parents?
thanks!
