Possibly, if the petition is filed promptly with complete evidence and premium processing is used, but the timeline should be built from the filing date, not the audit date. Do not schedule her as the audit lead until the petition is approved and she has been admitted.
Build the calendar from evidence readiness
Count backward from the audit. The affiliate will want the scientist on site with time to implement the protocol, train staff and run at least one validation cycle before the auditors arrive, which means arrival two or three months ahead. Petition preparation takes as long as the document collection takes; the version history and training rosters can be pulled in days, but a plain-language description that satisfies confidentiality reviewers may take longer.
Premium processing shortens the USCIS decision window for a fee, and a Canadian citizen can then present the approval at a port of entry. If the calendar cannot accommodate this, the affiliate should prepare a fallback: remote guidance from Canada on the protocol's documentation, with the scientist arriving after the audit to lead the corrective actions. Remote support performed from Canada does not require US work authorization; the same support performed on site does.
