I need to renew my US passport via the embassy in London. Unfortunately, DX, the courier that the embassy uses, does not operate in the Orkney Islands. DX says that I should send my application to the US Embassy in London via Royal Mail. I called the Embassy and they confirmed that I should send it via Royal Mail Special Delivery. I'm wondering if anyone else has done this, and has the process worked OK for you? I'm a wee bit nervous about doing something that is out of the usual process for the Embassy ...
