A business concern does not itself authorize U.S. work or establish the timing of the immigration process. Have the appropriate procedure and status reviewed before starting the assignment.
Prepare for uncertainty without promising an approval date
State the real readiness date and distinguish response planning from permission to work. If the proposed duties change after a system repair, reassess what knowledge the remaining U.S. role actually requires.
Business urgency does not guarantee approval or a particular completion date. A transfer meant to fix a production problem before a specific planting window has to be scheduled around USCIS, not the other way round. An initial new-office approval is limited to a maximum of one year, and later eligibility requires its own review and evidence. Verify that the foreign and US organizations have the required parent, branch, subsidiary, or affiliate relationship, that the foreign organization remains actively doing business, and that the US organization either remains actively doing business or qualifies as a new office. Trail construction has a fixed window between spring runoff and freeze-up, and a late approval costs a full season. The customer contract should make the onsite date conditional on immigration approval, with a remote-support alternative.
