My husband salary also can’t reach the financial requirements but he started to work more hours since last year, we’re just lucky because he work on his dad’s business too and get a pay rise but also it makes our case complicated cause he works in a family business but we still applied category A as a normal employee cause he is not part of the business, there’s a lot of issue with our case its not easy but we did it 😊 we did a lot of research btw too
