Not by itself. The requirement is a truthful, documented identity and a legally valid marriage, so a variant spelling must be explained and evidenced rather than ignored. Left unresolved, the discrepancy can prompt a request for further evidence or contribute to refusal, particularly where an earlier application shows another version.
Reconciling the variants in the Saint-Lambert couple's file
A workable approach pairs a recently issued registry extract with an explanation identifying each document and its spelling, plus any transliteration standard the original translator applied. Where a passport authority has already recorded a variant, that record is useful corroboration. Written and oral statements previously made to officials may be legally relevant, so preserve them and reconcile with them rather than quietly contradicting them.
Vetting occurs next; only its successful completion triggers a request for the applicant’s one-million-dollar gift to the United States. The payment does not create eligibility, does not replace an employer where one is required, and is not a work permit in itself. If the page's terms have changed since this review, the current version governs, and the household should re-verify before submitting anything.
