Most foreign nationals need a visa to enter India for a trade fair — there is no visa-free entry for UK, US, EU, Gulf or most other business travellers. Exhibitors and business visitors normally use the Indian e-Business Visa (applied online, typically about USD 80, one-year multiple entry, up to 180 days per stay, usually decided within roughly 4 working days). Shorter e-Tourist Visas start at about USD 25 for a 30-day validity and are fine for visitors who are only attending. Apply at least 2–4 weeks before travel, carry a printed copy of the Electronic Travel Authorisation plus the passport used in the application, and expect biometrics/interview only if you apply for a regular (non-e-Visa) business visa at a mission. Rules differ by nationality — verify on the official Government of India e-Visa portal before booking flights.
Estimated cost: Varies by visa type and nationality (check official site).
Processing: Varies by nationality; apply several weeks before travel.
One-year multiple entry, up to 180 days continuous stay; requires a business invitation or the event/organiser details and a passport valid at least 6 months. Single/double entry depending on nationality; reduced fee tiers exist for some nationalities. Not valid for selling or signing contracts on site.
