If you meet all the requirements of the immigration service, it is necessary to apply for an extension of your immigration status 3 months before your first UK investor visa expires.
Visa extension costs include:
£1,623 – an application fee which is paid when you apply for a visa extension;
Health surcharge is calculated on an individual basis;
£19,20 – a fee to collect your biometric information (fingerprints and photo) for a new residence card.
You can also pay an additional £500 for a priority service for each person. In this case, your application will be processed in 5 days instead of the 8 weeks under the standard procedure.
