Very few Indian companies are trading in US stock markets. Some are doing through the ADR route. an American depositary receipt (ADR) is a stock that trades in the United States but represents a specified number of shares in a foreign corporation. ADRs are bought and sold on American markets just like regular stocks, and are issued/sponsored in the U.S. by a bank or brokerage.
In reality it doesnt matter much for and Indian company to trade on US Stock markets through ADR route.
