If you are from a country that benefits from the Visa Waiver Program, you will not need to apply for a visa if your stay in the United States does not last more than 90 days and is by sea or by airway. However, the purpose of your stay must be either for business, for tourism or for transit.
In these cases, you will need to have an ESTA travel authorization . ESTA is an electronic travel authorization system that was set up with the aim of enhancing the security of travel to the United States. Indeed, the ESTA authorization allows the immigration officers who are at the border posts to have the data concerning you even before your entry on American soil. Obtaining an ESTA travel authorization means that your trip does not pose a threat to US security and does not conflict with US law.
