The concession creates a commercial timetable, not a guarantee of immigration processing. Review whether funding, premises readiness and the application evidence are sufficiently developed. If the opening depends on authorization that is still pending, discuss the consequences with the landlord before using an optimistic filing date to justify irreversible commitments.
Coordinate the lease clock with the work that can lawfully occur
Clarify who may conduct buildout and launch tasks if the investor cannot yet perform U.S. work. Ask whether the concession period can be adjusted by agreement and document any change. Canadian citizens generally need an E visa, and visa validity differs from authorized stay. Use actual approvals and admission requirements to plan personal work and travel.
Set your own milestones: landlord consent received, renewal answered, funds transferred and traced, packet reviewed. A first review should place the source transfer, commitment dates, opening milestones, and any visa appointment in one chronology. Applying before commitment fails the at-risk test; closing unconditionally before approval risks owning a U.S. business the buyer cannot lawfully run. Sequence the transaction so the funds are committed under terms that leave the investor exposed only to the appropriate immigration contingency, if any.
Fix dates for the entry list, the supporting documents, the signed memo, any amended filing, and counsel's review of the final set.
