India requires a valid passport and an advance visa for most foreign trade visitors, and there is no visa-on-arrival facility for business travel at Delhi. The standard route is the e-Business Visa applied online at indianvisaonline.gov.in, which covers trade-fair attendance, supplier meetings and business discussions; it is issued as a one-year multiple-entry visa with stays of up to 180 days per visit, sits in a government fee band of about USD 25–80 depending on nationality, and is normally processed within three to five working days. Apply three to four weeks before departure, carry a printed copy of the visa with your passport, and keep your return ticket, your hotel address in Greater Noida and the organiser invitation letter with your travel documents for immigration. Travellers whose nationality or purpose is not covered by the e-Visa categories apply for a regular business visa at an Indian mission, which needs several weeks of lead time.
Estimated cost: Varies by visa type and nationality (check official site).
Processing: Varies by nationality; apply several weeks before travel.
