Assign each quoted commitment and actual payment to the relevant employee or intended eligible family member, using the official instructions.
Avoid unexplained aggregate totals
A company spreadsheet may assist planning but should not be presented as a government receipt. Keep private professional charges separate and identify amounts not yet instructed or paid. If sponsorship changes, retain the history instead of silently reallocating one employee’s payment as proof that another has been approved.
The official process describes further USCIS instructions following the initial application, so the applicant should expect to produce the ordinary immigrant-petition evidence for whichever classification is assigned, plus whatever the program itself requests. The vetting file is personal: passports, civil records for the marriage and the children, addresses and travel history, and a frank account of anything in a person's background that might bear on admissibility, disclosed to an attorney early rather than discovered later. The principal should include any joining spouse and unmarried children younger than 21 on the initial online application; prepare each person’s passports, civil records, prior applications, relevant notices, travel chronology, and name-change evidence. A notice naming only the principal says nothing about anyone else, and the family’s position is established by each person’s own documents: civil records proving the relationship, each child’s date of birth, and the material addressing admissibility.
