File against the work Priscilla will actually do first, not against an optimistic launch. Allow several weeks to assemble the evidence, then USCIS processing, which premium processing can shorten for a fee, subject to any request for evidence stopping the clock.

Where the rollout is uncertain, the company faces a choice between filing early against a plan that may change and filing later against a plan it can support. The second is usually safer. If the schedule slips after approval, the account of her duties should be updated in the company's own records so that an extension filing is consistent with what happened rather than with what was projected.
Practically, allow a few weeks to pull the authorship and training evidence, remembering that her continuous qualifying year is measured at filing. As a Canadian citizen Priscilla presents the approval notice at a port of entry rather than obtaining a visa stamp. She should not begin the U.S.
