Dubai's expat Indians: The world's most productive foreign workers

Dubai Creek was once the heart the Gulf emirate's business activity, where boats and barges sailed along transporting goods and people to foreign ports.

From electronics to sporting goods, the Creek is still a vibrant trading base, but far from the integral shipping hub it once was.

For centuries this is where all Dubai's international business happened. Much of the goods bought and sold here went to India, which over time became the United Arab Emirates' largest trading partner.

In the 1970s, trade between the two countries amounted to $180 million a year. Today, this figure is closer to $75 billion.

With growing business ties, many Indians have moved to Dubai in search of work and opportunity -- but home is never far from their mind.

Shekhar Patni is one of almost 2 million Indians working in the UAE.

He moved here more than 30 years ago and decided it was a good place to set up his jewelery business. His company has since grown to be valued at more than $20 million.

"It's the culture, the mixed culture of India and the Middle East," Patni says on why he decided to settle in Dubai. "This is the more important for us. And it is very close to India."

As his native country awaits the outcome of parliamentary elections, Patni is watching closely even though he doesn't have a vote.

Patni says he sends a huge portion of his earnings home for his family, business and for investments.

He's far from alone in this endeavor.

Krishnan Ramachandran runs a wealth management group in Dubai that manages $400 million worth of assets belonging to Indians living in the UAE. The majority is re-invested in India.

"We cater to a wide range of clients starting from the person who's at the bottom of the pyramid to somebody at the top of the pyramid," said Ramachandran.
