India is a vast and diverse country where Hindi serves as a bridge language across the Hindi-speaking belt and as a widely understood second language in most urban centers. For expats working in India, returning diaspora, and OCI card holders visiting extended family, Hindi proficiency transforms daily interactions from transactional to genuinely connected.
The Aadhaar card is India's biometric identity system, linking a 12-digit unique number to fingerprints and iris scans. For foreign nationals residing in India for more than 182 days, Aadhaar registration is possible at authorized Aadhaar Seva Kendras with passport, visa, and proof of Indian address. OCI (Overseas Citizen of India) card holders can also obtain Aadhaar. The PAN card (Permanent Account Number) is required for all financial transactions above a threshold: opening bank accounts, investing, filing taxes, and significant purchases. PAN can be applied online through the NSDL portal. The OCI card (Overseas Citizen of India) gives lifelong visa-free entry to India for citizens of most countries who have Indian ancestry. For returning diaspora, updating Aadhaar and obtaining PAN are the first administrative priorities.
India's digital payment revolution has made UPI (Unified Payments Interface) the dominant payment system. PhonePe, Google Pay, Paytm, and BHIM apps are used for everything from auto-rickshaw payments to restaurant bills and utility payments. Opening a bank account in India requires Aadhaar, PAN, and proof of address. State Bank of India (SBI), HDFC, ICICI, Axis, and Kotak are major private and public banks. For OCI cardholders and NRIs, NRO (Non-Resident Ordinary) and NRE (Non-Resident External) accounts are available. Cash remains important in local markets, transportation, and smaller towns. Knowing how to discuss payments, ask for change, negotiate prices, and resolve billing issues in Hindi covers the majority of daily financial interactions for expats in India.
India's healthcare system is a mix of government facilities and private hospitals. Government hospitals provide low-cost care but often have long wait times. Private hospitals in major cities (Apollo, Fortis, Manipal, Max, Medanta) provide excellent care at significantly higher costs but still below Western equivalents. Health insurance in India: the PM-JAY (Pradhan Mantri Jan Arogya Yojana, also called Ayushman Bharat) covers below-poverty-line citizens. Private health insurance from Star Health, HDFC Ergo, or Niva Bupa is common for middle-class and expat residents. Pharmacies (medical stores, dawakhana, aushadhalaya) are widely available; prescription requirements are less strictly enforced than in Western countries. Ayurvedic medicine (ayurvedic dawa) from shops and clinics is widely used alongside allopathic treatment.
