The Embassy in London emailed me to say a one way ticket is fine because I said Iโm unsure of the exact date Iโd be coming home ๐. In terms of accommodation just go on Agoda and find a hotel that offers โpay at hotelโ and book it. You will then get a confirmation sent to your email which you can use for your application and then cancel it ๐. Then you are free to book what you want, when you want and where you want
yeh you Should be fine to do this from an embassy not in your hometown country. Number 7 on the application you would just upload proof of residency in the U.K. I.e passport I believe
