The Triangle's 'French Connection' runs deep in area

"We work together to bring France and French culture and French businesses to everyone in the triangle," she said.

"First off all it's smaller, not as expensive as the biggest metropolis you can see in the U.S. When they look at and compare prices between living and working in New York, Los Angeles and Chicago I mean the math is very simple," Ribeill said.

"This area is attractive because of the presence of three larger research universities.there's a large amount of highly trained people in biology and engineering," said Stefan Willemsen, CEO of Biomerieux.

The heavy French influence in the Triangle often goes unnoticed, but there are even French-speaking schools for children in what's become a comfortable landing spot for those coming to the U.S. for the first time.

"When people come to pick up a passport they say ah there's a school. There's a Chamber of Commerce," Ribeill said.

Ribeill also points to the recent addition of a non-stop flight from RDU to Paris as a reason for the French growth.
