有没有同学知道，如果是Tier 2，能不能自己开个公司？平时上班，业余自己做点小生意什么的。
读了一下网上的条款：
What you can and can’t do
You can:
work for your sponsor in the job described in your certificate of sponsorship
do a second job in the same sector and at the same level as your main job for up to 20 hours per week
do a job which has a shortage of workers in the UK for up to 20 hours per week
do voluntary work
study as long as it doesn’t interfere with the job you’re sponsored for
travel abroad and return to the UK
bring family members with you
You can’t:
own more than 10% of your sponsor’s shares (unless you earn more than £153,500 a year)
get public funds
start working before you get the visa
apply for a second job until you’ve started working for your sponsor
我记得以前是说，如果第二份工作是在正常上班时间之外的，是不用告诉Home office 的，也不用申请新的签证的。现在这种说法没有涉及到这一项。有没有了解的同学解答一下哈。
