The Home Office have just announced that their charges will rise by, typically, 4% from 6 April 2018.
Visit visas, Tiers 1, 2 and 4 visas, Spouse/partner visas, ILR and British Citizenship all increase by 4%.
There are a very few exceptions to this, such as EEA residence cards and replacement BRP cards which remain unchanged, and the priority service for out-of-country non-settlement (eg Tier 2) goes up 15% to £212 from £184.
So, a three year Tier 2 visa in-country charge increases to £704 by post, £1181 for the 10 day service and £1314 for the same day service. Out-of-country applications will now cost £610 for the standard service and £822 for the fast-track service.
ILR same day service charge increases to £2999 (postal application is £2389).
Suggestions that the Health Surcharge may double have yet to be confirmed (or denied).
