UK citizens need a visa to Uzbekistan, but they don't need a letter of invitation if they apply for visa in London. Registration in Uzbekistan is very important and unavoidable. To enjoy your stay, follow the rules and make sure you are registered promptly. By law, all foreigners must be registered within 72 hours of arrival (excluding weekends and public holidays, but including the day when you arrive, even if this is after office hours). It is not allowed to stay without registration, as this is illegal! If you leave the country within 72 hours of arrival you are free from registration.
You are welcome 😊
