I was considering a 2 year visit visa for the missus, just to save me further application/s in the following 18 months. It also means that she would have a visa in place which helps for any Schengen application.
However, I am struggling with the cost vs benefits analysis.
US$473 for a 2 year visa does not sound good value against US$125 for a 6 month visa. In my case the admin/traveling time savings do not justify an extra US$350.
The length of permitted stay is a minefield with everyone saying that there is no 180 day per rule - yet Immigration criteria pointing to the fact that if you spend longer in the UK, than your home country, then you are making the UK your 'main home'. Could you even get 3 x 6 month visit with a 2 year visa? - it seems to open up reasons for future refusal.
Am I missing something?
