I believe that as long as you can prove a stable income each week / month they do not or cannot expect you you have huge savings, I proved that I could save but did not have much money left in savings when I applied for a Fiancée Visa, most was spent on the application flights home as Anilyn was here on a Visit Visa before, as long as you prove you have disposable income each month to be able to support your new spouse and pay for flights etc then all should be well, hope this helps
