Your spouse's derivative eligibility runs through your case, so a change to the sponsoring entity is relevant to that file too. Each family member still has an individual admissibility assessment. Participation adds US$15,000 and a US$1 million gift; initial inclusion is officially recommended for program benefits, and later addition is neither impossible nor free.
Keeping the spouse's file consistent with the new sponsoring entity
Where the spouse's documents reference entity A — an employment letter, an address, an insurance record — decide whether they should be updated or explained. Independent work permission, if it exists on its own basis, is separate from the derivative case; a pending case does not itself authorise work. Where the household's answers must match, prepare them together so that one file does not contradict the other.
Sequence the household's paperwork so that nothing has to be unsaid. A spouse's file already naming the earlier entity can be updated or explained, but a statement made and then withdrawn is a different problem from one that was accurate when written. Hypothetical example: the spouse of a candidate sponsored by an affiliate supplying a specialty food-processing plant submits an employment letter naming the entity that no longer employs the principal, days before the change is confirmed.
Ask which of the household's documents depend on the sponsoring entity and hold those until the entity question is settled; the rest can proceed. Derivative eligibility runs through the principal's case, while each family member still has an individual admissibility assessment, so the two questions move on separate tracks.
