Anyway I am currently putting together a proposal for sposorship - I would most likely do this in either Africa or the US.
Good luck with that. You won't find many takers. Why would anyone want to sponsor when their files are full of people who already paid for their training themselves? By all means explore that avenue. But your best bet is to find the money yourself.
Sponsorship is rapidly becoming a thing of the past. I suspect the last few will disappear sooner or later. The only remaining sponsorships.will be those offered by countries who wish to favour their own people and reduce the numbers of foreign pilots flying for them. Even then that will fade as in effect most pilots come from a middle class background in most countries and as a rule they have some money to pay for their kids to become pilots. Much as anyone trains to be Doctor or whatever.
