Re-entry with IV stamp

[pow123 14]

My wife and I were both approved at Montreal (EB2-NIW) at the end of July 2022 and entered with our IV stamps first week of August 2022. My wife needs to travel back to Canada next week. Will she be able to re-enter alone with her endorsed IV stamp or do I need to travel with her as I was the primary applicant on the EB2-NIW?

She should have no problem.
