Hi,
I was on the phone with the international students adviser at our school about the issue of the 90 days countdown starting date (see my other post)
According to her, CIC tends to be very accomodating with this issueand that they are talking about extending the 90 days limit to 180 days in the next few weeks (probably in april ot may).
That's the info she gave me, I hope she's right and that the new rule would be retroactive.
I'll let you know about any further developement :)
