I am currently finalizing my DS-160 B1/B2 US visa application to visit the US to attend a workshop for 5 days in the US. In the invitation letter I received from the non-profit organization that is hosting the workshop, it is written that my scholarship is funded by BP, a global integrated energy company and a sponsor of the conference.
My question is: Regarding filling in the information about the entity paying for my trip, do I submit the contact details for BP, the corporate sponsor, or the non-profit organization receiving the sponsorship?
