The Electronic System for Travel Authorization performs checks against law enforcement databases. All travelers seeking admission to the United States under the Visa Waiver Program are required to obtain an electronic travel authorization using this system prior to being granted boarding.
If your electronic travel authorization application is approved, it establishes that you are eligible to travel, but does not establish that you are admissible to the United States under the Visa Waiver Program. Upon arrival to the United States, you will be inspected by a U.S. Customs and Border Protection Officer at a port of entry who may determine that you are inadmissible under the Visa Waiver Program or for any reason under United States law.
A determination that you are not eligible for electronic travel authorization does not preclude you from applying for a visa to travel to the United States.
All information provided by you, or on your behalf by a designated third party, must be true and correct. An electronic travel authorization may be revoked at any time and for any reason, such as new information influencing eligibility. You may be subject to administrative or criminal penalties if you knowingly and willfully make a materially false, fictitious, or fraudulent statement or representation in an electronic travel authorization application submitted by you or on your behalf.
WARNING: If upon application for admission to the United States at a port of entry you are admitted under the Visa Waiver Program (VWP) by a US Customs and Border Protection Officer, you may not accept unauthorized employment; or attend school; or represent the foreign information media during your visit under the program. You may not apply for: 1) a change of nonimmigrant status, 2) an extension of stay, or 3) adjustment of status to temporary or permanent resident, unless eligible under section 245(c)(4) of the Immigration and Nationality Act. Violation of these terms will subject you to REMOVAL.
