Your nationality is what matters. If you are a British Citizen then you do not require a visa. The visa office processing your file will be aware of this and you shouldn't have to send in your passport for final processing. Sometimes, however, they do request a copy of the biographical info page be sent to them.Do you know if that is the case even if you are from a visa exempt country (ie UK in my case) and living in one that wouldn't be exempt? Thanks!
