হাসপাতাল — Kolkata Metropolitan Area

India offers a 60-day double-entry e-medical visa to citizens of 165+ countries, processed in 72 hours via the official indianvisaonline.gov.in portal. Two attendants on e-medical-attendant visas can travel with the patient. The hospital's international patient department issues the invitation letter once your case manager confirms the booking — that's the single document the consulate needs.

Indira Gandhi International (DEL), Mumbai (BOM), Chennai (MAA), Bengaluru (BLR), and Cochin (COK) host direct connectivity from the GCC, the Gulf states, the UK, Singapore, Bangkok, Kuala Lumpur, and most major US gateways via single-stop. Air India, Vistara, Emirates, Etihad, Qatar Airways, and Singapore Airlines run dense schedules — typical total transit from London is 9 hours, from Dubai 3 hours, from JFK 14-16 hours single-stop.

Recovery hospitality is mature — most flagship hospitals (Medanta, Apollo, Fortis Memorial) maintain partner hotels within walking distance with medical-grade housekeeping (sterile linens, low-allergen cleaning, in-room nursing where requested). Plan 10-21 days between discharge and flight home for post-op clearance.

Delhi-NCR runs hot and dry March-June, monsoon July-September, and crisp October-February. Air-quality (AQI) is poor November-January in the north — patients with respiratory comorbidities should travel to South India (Chennai, Bangalore, Kochi) during those months. Mumbai is humid year-round, Bengaluru is moderate.
