The International Cycling Union has handed a four-year licence to Vincent Lavenu's team.
“Obviously, we are pleased and relieved with the decision of the licenses’ commission of the UCI," Lavenue said.
"This is the reward of a hard work alongside our sponsors, both to strengthen the team than to produce an administrative and financial file that have to meet all the UCI’s criteria.
"It is an honour for the Pro Cycling Team AG2R La Mondiale to compete on the World Tour.”
As the finals places on the Tour were decided, two-times Tour de France champion Alberto Contador's Saxo Bank-Tinkoff Bank team were given the green light, but Joaquim Rodriguez's Katusha were rejected by the UCI.
Meanwhile climber Axel Domont, 22, has signed a two-year contract with AG2R La Mondiale.
He has spent the last two years with Chambéry Cyclisme Formation, the squad's junior team, winning a stage of the Giro di Toscana this year.
