I am a US Citizen working in Canada for the last 3 years on a NAFTA Permit. When it was time to file for an extension, I put my soon-to-be ex wife's name on the application as she got an open permit for being my spouse. Question - will her permit be invalidated once our divorce is finalized? My employer stated that their policy is to notify immigration that the spouse is no longer the spouse of the principal permit holder, so I thought that meant that her permit would be invalidated. Please advise. Thank you!
