To get a UK Family visa, a British spouse or partner must have a minimum annual income of £18,600.
For visa extensions, when both spouses or partners have the right to work, their combined income could be considered.
If you add one child to your application, the required annual income will increase to £22,400. For each additional dependant, it will be further increased by £2,400.
The requirement applies to both married and unmarried couples.
This maintenance requirement applies to the first visa application, any visa extension, and the application for an Indefinite Leave to Remain.
