How long does it usually take to issue an expedited visa in the UK after electronic transfer?

If you are rejected for the first time, your second re-visa will be transferred by phone, and the visa officer will ask you some questions (such as why did you go to Britain? Where is England going? How many days will it take? And so on), you should try to answer calmly and don't show the tendency of immigration.

If it is urgent, it will take 3-5 working days from the second day of delivery.

It will not be adjusted on Saturday and Sunday, because the embassy is on holiday and no one goes to work.
