WSBI is not responsible of any administrative procedures regarding visas. We advise you to get in touch with the Indian embassy/consulate of your country/region to know about the formalities. Please keep in mind a certain delay might be necessary to get your documents in order, we recommend you to start with this process as soon as you register to the WSBI World Congress. It is not possible to get a visa at the airport once you arrive in India. It must be done prior to your trip.
