I'm just curious too, about your question: what difference does that make? There are so many with a full approval before March 18th, and aren't being allowed to enter.Just curious, is your passport stamped and/or do you have the Letter of Introduction with you?
There is no "exemption" in practice. This confusion is what I've been asking more information about.
While they go on announcing measures for PGWP eligibility for those who have just applied now, without even submitting a complete application.
I hope they clear out the situation for those with an approval too, instead of updates only for those with an in-process application. It's less about PGWP & more about critical on-campus lab work for some people at the graduate level who need to be there for the program.
