The eVisa is accepted at 28 designated airports including Delhi (DEL), Mumbai (BOM), Bengaluru (BLR), Chennai (MAA), Kolkata (CCU), and Hyderabad (HYD), plus 5 seaports. At the airport, proceed to the eVisa immigration counter with your printed eVisa confirmation. Biometrics (fingerprints and photo) are captured. India also offers traditional paper visas through the embassy with longer validity options for business and employment.

Direct flights from New York JFK to Delhi run about 14 hours 30 minutes on Air India. Newark to Mumbai runs about 15 hours 30 minutes on United and Air India. Chicago, San Francisco, and Washington Dulles also have nonstop service to Indian cities. India uses the Indian rupee (INR), trading at roughly 85 INR per $1. UPI (Unified Payments Interface) dominates digital payments in India: Google Pay and PhonePe are accepted at millions of merchants. Metro systems operate in Delhi, Mumbai, Bengaluru, Chennai, Kolkata, and Hyderabad with fares from INR 10 to INR 60 ($0.12 to $0.70). Auto-rickshaws are the universal last-mile transport: use the Uber or Ola app for metered pricing.

IAH has no direct rail link to downtown Houston. The IAH Express bus runs from Houston Amtrak/Greyhound station via Park & Ride to Terminal C (60–90 min, $1.25 with METRO Q card). This is the only transit option; Houston's rail network does not reach the airport.Taxis from downtown Houston cost $50–70 and take 40–60 minutes. Ride-hails (Uber, Lyft) are typically $35–55. IAH sits 23 miles north of downtown on the North Freeway (I-45); traffic is heavy during morning and evening rush. Remote economy parking lots serve all terminals via shuttle.

Airport Express Metro from T3 to New Delhi Railway Station (18–20 min, ₹60) runs 5am–11:30pm. T1 (domestic departures) has a free shuttle to T3 for the metro. Prepaid taxi booths in arrivals offer fixed fares; the New Delhi railway area is ₹400–600.Ola and Uber are reliable from DEL and often cheaper than prepaid taxis. Delhi traffic is severe; plan 60–90 minutes for surface transport during peak hours even though the airport is only 15 km from Connaught Place. NH-48 expressway provides the main access road.

Semi-arid climate with extreme seasonal variation. Summers (April–June) are extremely hot (38–46°C). Heat affects ground crew capacity but flights operate normally. Monsoon season (July–September) brings heavy rain and severe thunderstorms that frequently cause delays and diversions. Dust storms (andhi) precede monsoon onset in May–June and reduce visibility to near zero within minutes.

Dense fog is the most disruptive winter condition. December and January bring persistent cold fog (5–10°C with near-zero visibility) that can shut down operations for hours each morning. Delhi is one of the foggiest major airports in Asia during this period. Autumn (October–November) and spring (February–March) are the most flight-stable windows.
