No. The official material describes steps and vetting but not a guaranteed date, and the final classification is subject to visa availability. Business decisions should follow actual instructions and approvals, not projected ones.
Let the government's instructions set the pace of the wind-down
The contractor still holds two cutting contracts that run through the next winter, and the broker has suggested he assign them now so that he can move within months. The official framework describes an application, a fee, further instructions from USCIS with supporting documents, vetting, the gift on instruction, and then placement in an immigrant classification subject to visa availability. None of those steps carries a promised duration, and the program's terms may change while an application is in progress.
The sensible sequence is to keep the contracts running, apply, respond to instructions as they arrive, and treat the point at which the gift is requested as the first moment a move date becomes realistic. Assigning contracts early to meet a broker's schedule would leave the family without income during a process whose length nobody can guarantee. If the terms change materially before the gift is made, the household should be free to stop, which is another reason not to borrow against the plan or dismantle the business in advance.
