A later opening means more months of living costs before the business pays anyone. Budget those separately from the investment so household spending is not quietly drawn from committed capital. A legally married spouse who holds valid E status is generally employment-authorized, but that is a separate process and not a guaranteed second income by a fixed date.
Keep living costs out of the investment column
List rent, insurance, schooling and transport for the months between arrival and revenue, then say where that money comes from. Unmarried children under 21 may accompany an eligible parent, but dependent status gives them no work authorization. If the spouse intends to work, confirm the evidence an employer will accept — the admission record and, where applicable, an E-2S notation — before counting on that salary in the plan.
Compare the schedule the business runs on against the one a child's status runs on, since the two are not synchronised. Dependent eligibility for an unmarried child ends at a defined age, and a launch that slips postpones no birthdays. Where a child sits close to that line, raise it at a first consultation rather than after the delay, because the alternatives available then are wider.
Keep the spouse's position separate from the child's too: authorization to work attaches to the spouse's own valid status and documentation, not to the household, and an employer will ask to see the record establishing it before adding anyone to a payroll.
