想请问坛子里的去过英国的兄弟姐妹，我7月份去英国开会，之后想在英国玩几天，该办visitor签证还是business签证？而且我看到申请网页上说：

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:
( X* \2 n4 ?8 E$ l; c
6 w0 d1 S' e+ z    a visitor visa
! G1 _/ G% [7 Z0 C% I    a Tier 5 (Temporary worker - creative and sporting) visa
    an EEA family permit
