According to The Wall Street Journal, you can expect it in your country soon. It claims that "people familiar with plans for the game said it would likely be available in other regions, including Europe, Japan, and other Asian nations within a few days."

This bodes well for an official Indian release. Even more so when you consider that previous Nintendo efforts such as Miitomo have ignored the country altogether.
The news comes days after developer Niantic had to pause Pokemon Go's global rollout due to server overcapacity.
The impact of players in other countries sideloading the game, in addition to those in countries where Pokemon Go is available, is that the game has been uplayable for a vast number of people due to its servers unable to deal with the load. So much so that developer Niantic who made Pokemon Go along with Nintendo and The Pokemon Company is delaying its release in other markets till this is fixed.
"We thought the game would be popular, but it obviously struck a nerve," Niantic CEO John Hanke said to Business Insider, stating that the launch in other countries has been "paused until we're comfortable". Despite the rabid interest the franchise has generated over the years, something Niantic is aware of, it has been caught by surprise.
