Hmmm... 2-part question;
I've done the 2 land borders using visa exemption already this year
However:
... if I come by land crossing next time but *with a non-b for work*... then, is that allowed?
2nd part: if yes, that's allowed to be done, and therefore it gets me in for 90 days [in which time the full year extension must be done] during those 90 days can I get a re-entry permit, leave for 3 weeks and return on a still valid non-b? (Getting the full year extension once I'm back)
My school couldn't confirm or deny whether a re-entry permit works for people in those initial 90 days/prior to having the 1 year extension
As always, thanks
