I'm applying to join my husband in the UK. So I chose settlement on both the Reason for Visit and Visa Type. Then it asks for visa sub-type. There are two relevant options; one for wife, and one for marriage. Which is the correct one? For the marriage one, a dialog box pops up and says the only form I have to complete is a "Sponsorship Undertaking Form". For the wife one, it says I have to fill out Appendix 2(which I know I have to do) and the Sponsorship Undertaking form IF you are a dependent or parent(which I'm not so I can ignore that?)
