EB23 雇主与雇员的亲属关系可以不公开么

因为是已经差了至少三代，很远，而且姓也不一样。如果我不disclose这个信息，移民局也没法查吧？难不成派人到实地采访问其他人？

A familial relationship includes any relationship established by blood, marriage, or adoption, even if distant. For example, cousins of all degrees, aunts, uncles, grandparents and grandchildren are included. It also includes relationships established through marriage, such as in-laws and step-families. The term marriage will be interpreted to include same-sex marriages that are valid in the jurisdiction where the marriage was celebrated.)

该提交最好提交，免得后患。  

实体考察也不是完全不可能？好像H1B就有随机实地考察
