Hey Everyone! I'm just in the process of renewing my US passport through the embassy in London and have arranged a collection from DX tomorrow. When I spoke with them, I was told that there are no appointments and that the courier could arrive any time between 8am and 6pm. Has this been the experience of others who have used this service (which is the only option as you cannot apply in-person or use Royal Mail anymore, apparently)? Also, they require pre-payment and took credit card information over the phone today, which I find a little unsettling...
For those who have been through this process recently, have you had any experiences that others should be aware of? And, other than the renewal form, photo, payment info page, and current passport, is there anything else you should send with the courier (return envelope, etc.)?
Apologies for the long-windedness and thanks in advance for any responses!
