Do British children need face-to-face visas?

No face-to-face visa is required for children's visas. It's the Guardian that needs to be interviewed, not teenagers under 18.

June 20 13: The visa interview in the UK has officially started, but not all visa applicants need to face-to-face interview, and the interview is still conducted by lottery. It's just that applicants need to go to the British visa center to submit visa materials and leave their biometric fingerprints, which is essentially different from face-to-face signing. Up to now, the probability of face-to-face signing in Britain is about 10%.
