背景：2个月前申请的妈妈，现在开始申请爸爸
Part 3: information about the immigrants you are sponsoring:
第一题，我选了Yes （Part 2中的信息是我爸爸的信息）
第二题： I am sponsoring the following family members immigrating at the same time or within 6 months of the principal immigrant name in Part2 (do not include any relative list on a separate visa petition) 是否需要选呢？
第三题： I am sponsoring the following family members who are immigrating more than 6 months after the principal immigrant (我觉得这个应该是不用选的）？
后面是否需要在family member 1 里填我妈妈的信息？
第29题 enter the total number of immigrants you are sponsoring on this affidavit which includes the principal immigrant listed in part2, any immigrants listed in part 3, item 1-28.....do not count the principal immigrant if you are only sponsoring family members entering more than 6 months after the principla immigrant. 这里是填1还是2 呢？
谢谢
