Apply for a UK Visa Online
Different from most other countries in Europe, to visit the UK, you have to apply for a visa separately. You can apply for the visa online on the internet. After that, you can start to complete all the requirements for the application, such as passing the b1 test which you can take through http://britishlifeskills.com, for example, to get a visa for immigration.
After completing the UK Visa application online, you will receive an email message containing the application number also known as the “GWF reference number”. You should note the number as it should not be lost or forgotten.
Then, you will be directed to an online appointment service owned by a commercial partner of the British embassy to make an appointment at the visa application center. The appointment should be no more than 90 days after the date you complete and submit the form for the UK visa application online.
