You will find many engineering groups (ACI, etc.), codes or standardization organizations that have local chapters and frequent meetings. - It is a good way to keep current as you know the languages are either "British", "American" or "English". Also, some European groups have some good meetings.
I am more familiar with southern India (Mumbai/Bombay, Chennai/Madras, Bangalore (high tech manned by many high school and college students)and others, but learned that the British did a great job of pulling 17 different areas with different languages together and provided a structure (not all good) that has produced a tremendous system that works well and is equipped to use the assets of educated people. I still do not understand why they resist sharing some of information and products elsewhere.
Working for a U.S. firm, you will obviously have some technical support and connections. There is also an "underground" group of engineers that are "expats" working privately in India. I met many of them at the "library" or social club at the better Hotels where they have a minimal cost membership that allows admission and benefits, which they use several times a week. They use this to meet others from different countries and share information on travel problems and country differences. When you get invited to a cocktail party at their home and meet people from TATA, Larsen Toubro and other huge technical firms that have many facets (engineering, construction, power production, education, cement production and many others), this can open many doors to other technical contacts and resources.
My friend in India was devastated when his daughter (structural engineering student) was not accepted to the Indian Institute of Technology and she had to go to MIT, Stanford or similar U.S. school. - It is a very private and proud country that has tremendous technical power
