thanks terpe for the link.
sorry i think i did not make myself clear with the bad back lol
my husband is sick and needs me there to take care of him, i am thinking of also including my husband medical records or sick notes from doctor to include on my application to prove my husband needs me as much as i do need to get over there. i just thought it will help.
in the application form it is asking who is paying for the travel to go UK, as in my case, it would be my sister instead of hubby as she wants to go with me and meet up my in laws
