If you have temporary permission to stay (for example, as a visitor) in the country where you are currently living, you cannot apply for most types of UK visa in that country. You can only apply for:

    a visitor visa
    a Tier 5 (Temporary worker - creative and sporting) visa

我是学生，持中国护照，那是不是我只能申请visitor签证？但是好像visitor签证的话又不允许你在英国参加会议啥的。。。那我到底该申请什么签证啊？
