背调HireRight的信息

请教地里：背调HireRight，只要求填写了（美）学历信息，没有前雇主信息。
但acknowledgment里提到: The types of background information that may be obtained
include, but are not limited to: criminal history; credit history; verification of your education, employment and earnings history.

不知道会不会还要调查前（国内）雇主？入职时间又会延长了。

谢谢前辈经验。。
