Non -Indian nationals will likely need a 'conference visa' before arrival.
Please wait for us to share with you necessary documents before you apply for visa in the Indian embassy/consulate in your country. Before this, we will reach out to you for necessary details to obtain these documents from the Government of India.
Update: Thank you for sending the passport information. We have applied for clearance certificate from the Ministry of External Affairs, Government of India. Please wait for this document before you apply for a visa. Please ignore this if you do not need a visa.
