@Robert ******
no... I didn't wait until the last day, my new school had prepared to have everything done by day x.
They told previous employer (at least 2 weeks prior to day x) to cancel things on day x.
But when day x came, some documents weren't completed yet.
This forced me on to overstay and I was just letting OP know it can still be done if you end up on overstay but best to try and arrange it so that doesn't happen.
