Mr Hollande says France is committed to destroying IS. French air strikes hit the militants in Syria overnight. IS has said it carried out the attacks on bars, restaurants, a concert hall and a stadium in which 129 people died.
A huge manhunt is still under way for a suspected member of the group, Salah Abdeslam, who was believed to have fled across the border to his native Belgium.
Interior Minister Bernard Cazeneuve told France Info TV that 128 raids on suspected Islamist militants had been carried out overnight on Monday to Tuesday. More than 160 raids were made earlier on Monday, with 23 people arrested and dozens of weapons seized.
Belgium's government has raised its terror threat level because of the failure so far to arrest Abdeslam, causing Tuesday's football match between the national team and Spain to be cancelled.
The BBC's Barbara Plett Usher, who is travelling with Mr Kerry, says his visit to Paris is to demonstrate Washington's support for a key ally.
In the wake of the attacks, the two countries have tightened their military co-operation, boosting the exchange of intelligence to help French air strikes against IS.
Meanwhile early on Tuesday, French warplanes carried out fresh strikes against the IS stronghold of Raqqa in northern Syria, the army general staff said, destroying a command centre and training centre.
