Do not infer that from record custody. Identify the actual sponsor, applicant roles and the separate instructions for the household.
Separate employer evidence from family eligibility
The intended eligible spouse and unmarried children under 21 should be included initially at US$15,000 plus a US$1 million gift each. Employer document access does not prove those relationships, individual eligibility or completed family processing. Separate the questions the employer can answer from those it cannot.
An employer may confirm employment, dates, duties and, in a corporate-sponsored case, whether it has identified this employee; it cannot establish a marriage, a parent-child relationship or a family member's admissibility, and it has no role in producing their civil documents. Hypothetical example: a landscape maintenance and grounds-management company assures a worried employee that it will handle everything for the family. Ask what that means in practice, name the specific documents each family member must still obtain personally, and put the list in writing so nothing sits in the space between two parties who each believe the other holds it.
Note as well that the intended eligible spouse and unmarried children under 21 should be identified at the outset, that each adds US$15,000 processing and a US$1 million payment to the U.S. government, and that this applies in corporate cases too, so a family member added late is a financial question as much as a procedural one.
