Volunteer What happens if I don’t pay my minimum donation? Your overseas project donation is due 1 month before your project departure date. If you cannot make the donation by then you must contact Vision Aid Overseas to discuss your situation immediately. When you join an assignment team (around 6 months before your departure date) you must sign a declaration pledging to make the overseas project donation to Vision Aid Overseas. Non-payment can result in serious disruption to your assignment and you may forfeit your right to travel and be held responsible for any costs incurred by the charity.
