目前的签证是申请ACCA签下来的，但现在又拿到MASTER OFFER 想去读，请问签证怎么转？需要重新申请CAS吗？谢谢大家。
这个要看你要读master的学校的要求，现在大部分学校都要求重新申请签证的
HO的规定是，现在的签证如果是09年10月5号以前申请是，只要发邮件通知就可以了，10月5号以后的，分情况的，具体如下
If you applied for your Tier 4 student visa on or after 5 October 2009
If you want to leave your current course in order to study the same or a different course with a different education provider, you must apply for a new Tier 4 visa. The new education provider must be a licensed Tier 4 sponsor, and must assign a new confirmation of acceptance for studies to you.
You can start your new course before we have approved your new Tier 4 application if:
you have applied to us for permission to stay and study with a Tier 4 sponsor which has a highly trusted sponsor rating; and
your permission to stay and study in the UK with your former sponsor is still valid; and
your prospective Tier 4 sponsor has assigned a confirmation of acceptance for studies to you for your new course.
You will start your new course at your own risk, as we may refuse your application.
You cannot start your new course until we have approved your new application, if you are applying to us for permission to stay and study with a sponsor that has an A (Trusted) or B (Sponsor) rating.
If you are already studying in the UK when you decide to change to a different Tier 4 sponsor, you must make your new application from inside the UK.

HO的规定是这样，但是每个学校也都有自己的规定和要求，你还是先去问问你的学校吧
非常感谢。
LZ,我想问下，你申请ACCA签证的时候，需要提供你申请ACCA课程所用的资料吗？或者只提供ACCA学校给你的证明就可以了。
