Her file has its own admissibility, so her declarations are assessed on their own facts, while her derivative place depends on your case succeeding. Since both of you describe one employer, reconcile the timeline once and use it in both files. Do not let one spouse's version be corrected while the other's is left standing.
One shared record, two responsibilities
Assume a hypothetical: she signed a form in 2019 naming the pre-merger entity, and you named the post-merger one for the same year. Both can be true if the dates are set out. Each of you answers for your own signature, and her joining place still carries US$15,000 plus a US$1,000,000 gift when instructed. Independent work permission, if she holds any, is separate.
The intended eligible joining spouse and unmarried children under 21 should be included initially under the FAQ. A derivative spouse relies on the qualifying relationship and principal case. Derivative inclusion rests on a legally valid marriage that the record can show. Comparing every prior form each family member has signed for the same employer or the same event, before submitting anything new, catches a mismatched date or title while there is still time to fix it. Reconciling a discrepancy with a written explanation, attached to both files, is more useful than leaving one version uncorrected and hoping no one notices the difference. An underlying fact can be accurate even when two earlier forms describe it differently, but an unexplained gap between related files can still raise, during review, a question that a short, dated clarification would have helped avoid.
