Getting set up in India
1
Legal & IDHigh confidence
Employment visas, e-FRRO and the 14-day clock
India's employment visa is employer-sponsored and carries a minimum annual salary threshold. Registration with the FRRO is mandatory within 14 days of arrival for visas valid over 180 days, done online through e-FRRO. Chennai's FRRO handles a substantial foreign population — the manufacturing sector brings significant Korean and Japanese communities — and is used to the process.
2
DrivingMedium confidence
The Tamil Nadu RTO, the OMR, and driving in a flood city
You may drive on a valid foreign licence with an International Driving Permit for a limited period after arrival, then need an Indian licence from the RTO covering your address. The Chennai-specific consideration is water: the city floods in the October-to-December north-east monsoon, and a stalled car in standing water is an expensive and common outcome. Know your route's flood points before November.
3
BankingMedium confidence
Opening an Indian bank account as a foreign national
Which account you can open depends on your residential status under FEMA, not your visa. A foreign national resident in India for employment can generally open an ordinary resident savings account. Everything requires a PAN card and thorough KYC. Chennai's advantage is that the manufacturing sector's Korean and Japanese communities mean several branches handle foreign customers as routine.
4
HealthMedium confidence
One of India's best hospital cities, and post-flood disease
Chennai attracts a very large share of India's medical tourists, which means an unusual concentration of specialist private care — Apollo was built here into a national chain, and Sankara Nethralaya is among the world's leading eye hospitals. The local health pattern follows the water: dengue and leptospirosis rise after the north-east monsoon floods, and heat illness is a genuine risk from March to June.
5
TelecomMedium confidence
Getting an Indian SIM as a foreign national
India requires full identity verification for every SIM, and for foreign nationals that means passport, visa, photographs, local address proof and sometimes a reference, followed by verification. SIMs issued to foreigners carry validity tied to the visa. In a city that floods and loses power, a charged phone with working data is also a genuine safety matter in November and December.
6
TaxMedium confidence
Indian income tax, metro house rent allowance and the April year
You are tax-resident in India if you spend 182 days or more in a financial year, or 60 days or more in the year plus 365 across the preceding four. The new regime has been the default since AY 2024-25 — lower rates, very few deductions — with the old regime available by election. Note the section number changed: it was section 115BAC of the Income-tax Act 1961, and since the Income-tax Act 2025 replaced that Act on 1 April 2026 the new regime sits in section 202. Chennai has always been in the top house rent allowance band, though from FY 2026-27 it shares that band with four more cities rather than three.

Language
Essential Tamil phrases
VanakkamGreetings
vah-NAH-kum
Hello in Tamil, with palms together. Tamil identity is strong here and a genuine attempt at the language is noticed more than in most Indian cities.
NandriGreetings
NUN-dree
Thank you in Tamil. Learn this and vanakkam before anything else — Hindi is much less useful in Chennai than in the north.
Filter coffeeFood
—
Degree coffee, made with a metal filter and served frothed between a tumbler and davara. A genuine institution and an entirely different thing from what that phrase means elsewhere.
OMRTransport
oh-em-ar
Old Mahabalipuram Road — the IT corridor running south along the coast, where most technology employment sits. Also called Rajiv Gandhi Salai.
MadrasDaily life
mah-DRASS
Renamed Chennai in 1996, but still used affectionately, especially in 'Madras Day' and by older residents. Both are understood.
MargazhiCulture
MAR-gah-zhee
The Tamil month spanning mid-December to mid-January, and the world's largest classical music and dance festival — hundreds of concerts across the city.
Idli sambarFood
ID-lee SAM-bar
Steamed rice cakes with lentil stew — the standard breakfast, eaten daily by most of the city and available on every street.
AnnaSocial
UN-nah
Elder brother in Tamil, used to address any man of similar or slightly greater age. 'Akka' is the equivalent for women. Using them correctly is basic courtesy here.
Share autoTransport
—
A shared autorickshaw running a fixed route for a few rupees. A genuine local transport layer that most newcomers never work out how to use.
North-east monsoonEmergency
—
Chennai's main rains come in October to December, not the June-to-September south-west monsoon that soaks most of India. This catches people who arrive expecting the national pattern.
Sandhya kaalamDaily life
SAND-hyah KAA-lum
Evening time, when the city comes out — Marina Beach, the temples, the coffee shops. Daytime Chennai in April is for indoors.
112 / 100Emergency
—
112 is the national emergency number. 100 for police and 101 for fire still work and are more widely known.

What to know before you go
Chennai's rain comes in October to December, not June
CriticalMost of India is soaked by the south-west monsoon from June to September. Chennai gets the north-east monsoon instead, from roughly October to December, and that is also Bay of Bengal cyclone season. The 2015 floods and Cyclone Michaung in 2023 both hit in this window. If you arrive in July expecting monsoon and find it dry and 38°C, this is why — and it means your flood risk assessment should be about November, not July.
Ask about both flooding and water supply — they are different problems
CriticalChennai has flooded catastrophically and nearly run dry within a few years of each other. In 2019 the main reservoirs effectively emptied and the city ran on tankers; in 2015 and 2023 large areas were underwater. Ask a prospective landlord two separate questions: does this area flood in the north-east monsoon, and where does the building's water come from in April and May. Neither answer predicts the other.
Register with e-FRRO within 14 days if your visa is over 180 days
CriticalEmployment visa holders with a visa valid over 180 days must register with the FRRO covering their Chennai address within 14 days of arrival. Fully online through e-FRRO, no agent required. You need passport, address proof, appointment letter, employment contract and proof of annual income.
Get a PAN card immediately
CriticalThe Permanent Account Number gates banking, salary and most financial transactions, and without it your employer must deduct tax at a higher rate. Foreign nationals can apply online. Start it in week one.
Tamil matters here more than Hindi
ImportantTamil Nadu has a long history of resisting Hindi imposition, and Tamil linguistic identity is genuinely strong. English works fine professionally and in the IT corridor, but Hindi is much less useful than in Delhi or Mumbai, and assuming otherwise reads badly. Learning vanakkam, nandri and a handful of Tamil courtesies goes further here than almost anywhere in India.
The heat is humid and relentless from March to June
ImportantChennai sits at sea level on the Coromandel coast, and April and May combine high thirties with high humidity, which is considerably harder to tolerate than Delhi's dry heat at the same temperature. Air conditioning is essential, power backup matters, and the local rhythm shifts to early mornings and evenings. Agni Nakshatram in May is the peak, and locals genuinely plan around it.
Work
Top industries & employers
Automotive manufacturing
Hyundai, Renault-Nissan, Ashok Leyland, TVS, Daimler India
Chennai produces a very large share of India's car exports and is often called the Detroit of India — Hyundai's Indian manufacturing is based here and the supplier ecosystem around it is vast.
Technology & IT services
TCS, Infosys, Cognizant, Zoho, Freshworks, Accenture
The OMR corridor is one of India's largest IT clusters, and Chennai is unusual in having produced two globally significant product companies of its own in Zoho and Freshworks.
Healthcare & medical tourism
Apollo Hospitals, MIOT, Sankara Nethralaya, Fortis Malar
Chennai attracts a very large share of India's medical tourists, and the resulting concentration of specialist care is a genuine advantage for residents.
Electronics & hardware manufacturing
Foxconn, Pegatron, Samsung, Nokia, Salcomp
The Sriperumbudur belt west of the city has become a major electronics manufacturing cluster, including significant iPhone assembly capacity.
Financial services & back office
World Bank, Standard Chartered, HSBC, Bank of America, Scope International
Substantial global back-office and technology operations, weighted to banking operations and analytics.
Film & media
Kollywood studios, AVM, Sun TV Network
Tamil cinema is one of India's largest and most influential film industries, and it is culturally central here in a way that is hard to overstate.

Where to go in Chennai
Marina Beach
Nature · Central seafront
One of the longest urban beaches in the world, running about 13 kilometres, and the city's evening living room.
Local tip: The sea here has strong currents and swimming is not advised — this is a walking and eating beach, not a bathing one. Come at sunset for the bajji stalls and the crowds, which are the point.
Kapaleeshwarar Temple & Mylapore
Culture · Mylapore
A 7th-century Shiva temple with a towering carved gopuram, at the heart of the city's oldest neighbourhood.
Local tip: Walk the four Mada streets around the temple tank in the early morning, when the flower market is running and the neighbourhood is at its best. Dress modestly; non-Hindus may not enter the inner sanctum.
Mahabalipuram
Landmark · 60km south along the coast
A UNESCO site of 7th- and 8th-century Pallava rock-cut temples and monoliths carved directly from the granite shore.
Local tip: Go early on a weekday. The Shore Temple gets the crowds; the Five Rathas and Arjuna's Penance are better, and the unfinished carvings on the hill above are free and almost empty.
T. Nagar & Pondy Bazaar
Neighborhood · Central Chennai
One of the highest-turnover retail districts in the world by area, especially for silk saris and gold.
Local tip: Genuinely overwhelming during wedding season and Diwali. Ranganathan Street is the famous crush; go on a weekday morning or not at all. The silk shops are the real reason to come.
Theosophical Society gardens
Nature · Adyar
260 acres of quiet gardens at the Adyar estuary, containing one of the largest banyan trees in the world.
Local tip: Free, open mornings, and an extraordinary pocket of silence in a city of eight million. The great banyan's aerial roots cover a huge area — walk under it.
Pulicat Lake & the Dutch cemetery
Hidden gemNature · 60km north
India's second-largest brackish lagoon, with flamingos in winter and the ruins of a 17th-century Dutch settlement beside it.
Local tip: Almost nobody from Chennai goes north. Flamingo season is roughly November to March, the same months when the weather is bearable, and the Dutch cemetery with its carved tombstones is completely deserted.
