看说是所有私立学校都不能打工,那么如果4月21号之前去签呢??
From summer 2011 students who are applying for
entry clearance or leave to remain and who are not
sponsored by a higher education institutions or
publicly-funded further education college will not
be granted permission to work at any time during
their studies.
是不是说从2011年夏天开始实施,还是说4月21就开始实行了???
