Hi, i am wanting to send my father a visitors visa and i have some questions if anyone can help me thanks 
1. Proof of means of financial support.
My father does not work, doesnt have any money in his bank account. Keeps cash only. And doesnt work.
What can he or i do to prove any of this? Because me and my husband will be paying for everything and we both work full time.
2. Didgital photo
Since this application is online does he need two photos and do they need to be sign and dated? Thanks
3. Purpose of traval
It asks for scanned flight tickets? Do i buy the tickets after he gets the visa or before he gets it?
your traval itinerary? He will be staying with us what can i show them for that?
And prood of medical appointment
