I am an Indian citizen (and resident) traveling to Rio de Janeiro, Brazil as a volunteer for the Olympics in Aug 2016, at the invitation of the Olympic Committee. However, all expense of travel and stay is on us. Only food and transport is free, that is, given by the Rio Olympic Committee.
I have already purchased my flight return ticket and paid all expense towards stay to Airbnb.
How much balance in my savings account should I show while applying for a visa?
What extra financial supportive document can I give?
Can I give FD certificates and share certificates?
I have all documents ready.
