回复：谢谢，还有一个疑问

Part D.  Other information
 

1. If separate petitions are also being submitted for other relatives, give names of each and relationship.
 

 

如何填写?
 

现在是给父母同时申请，给父亲的表格上是否要写上给母亲申请，-Yes.
 

如果是， 当然母亲的表格也要写了。 -Yes.
 

 

另外，大约一个月前，为姐姐提交了申请，是否也要填上。-Yes. But don't count your sister in your family size in the I-864s for your father and mother at this time because it takes about 10 years for your sister to immigrate to US.
