EVUS is the acronym for Electronic Visa Update System. It is an online program created by the department of Homeland Security and implemented by the Unites States Customs and Border Protection (CBP) As it names suggests, EVUS was created to update an individual’s biographical data periodically.
EVUS became effective on November 29th, 2016 as a security measure and travel requirement for those people who have a People’s Republic of China passport and hold a B1, B2 or a combined B1/B2 visitor visa. All chinese nationals should enroll with the EVUS before they travel to the U.S.
The application process is actually very simple and quick. The EVUS enrollment might take up to 20 minutes to complete. Each person is assigned an enrollment number that can be used to track the status of their EVUS. In the majority of cases, the status is cleared within a few minutes. However, it is strongly advised that all applicants register at least 72 hours before their departure to the U.S. If you do not have an EVUS upon arrival to this north american country you will be denied entry.
It is important to point out that the EVUS is not visa and does not work like one. All foreign nationals who travel to the United States of America should have a valid entry Visa. If you do not have a valid passport or a valid 10-year visitor visa you should not apply for the EVUS.
Once you have enrolled, the EVUS is valid for a period of two consecutive years or until your passport or visa expire. If any of the two occur, you should enroll again when you receive the new passport or visa.
