French citizens who intend to visit the United States of America for tourism or business-related trips of up to 90 days are not required to obtain a visa. French travelers are eligible to apply for a 2-year visa waiver under the US ESTA authorization.
An approved ESTA authorization is valid for entry into the United States by air or by sea, allowing visitors to arrive in the US by plane or by boat.
French citizens who wish to live in the US for work or study do require a visa and should contact a United States embassy or consulate in their country of residence. Additionally, if they wish to remain in the United States for longer than 90 days, you are obligated to obtain a US visa instead of the ESTA.
French citizens who already have a valid visa for the United States are not required to apply for travel authorization through the US ESTA visa waiver system.
