Wondering if anyone else was able to get this change by flagpoling? My partner is in the same situation (OWP needed to remove medical restriction, medical exam done and received, from EU) and we tried to flagpole today. Unfortunately she was told she cannot make the change at the border (St Armand entry). However, no clear reason was provided for why, except the officer saying she must do it inside Aanada. The current waiting time fo 90 days for this change would mean she loses a job offer.
Anyone know if its worth to try again at a different port of entry? I found several people saying they succeded in this and others not, do CBP officers sometimes refuse to process these kind of thigns based on some whims?
