Is it true that only the US has a visa interview requirement and other countries do not in UK/Canada?

No, it's not true that only the US requires a visa interview. The US generally requires all student visa applicants to attend an in-person interview.

Other countries like the UK and Canada may also require interviews, but these are less common:
- UK: Interviews are not routine but may be required for some applicants, usually by video call, to check the genuineness of the application.
- Canada: Interviews are rare and only requested if additional information is needed.

Visa interview policies are subject to change.
