India is a very large and diverse country. Despite many commonalities such as religion and weather, the east west north and south India have distinct variations in culture, food, music and attire. There are even variations in language at state level. 

There are 28 states and 8 Union territories in India. Union Territories are administered by the President through an Administrator appointed by him/her. 

Besides the mega cities  Mumbai, Delhi, Calcutta, Bangluru and Chennai, smaller towns such as Udaypur, Jaipur, Ahmedabad, Agra, Amritsar, Pune also attract a good number of visitors. Indian government promotes tourism under “Incredible India” slogan. 

Recent devaluation of Indian currency provides an opportunity to get more bang for your bucks. Although, prices have reason sharply in India due to constant inflation. 

Law and order tend to be generally good. However as a foreigner, be extra careful as they are targets of mugging in less populated areas at night.
