ESTA: Electronic System for Travel Authorization

  • ESTA is not a visa. It does not meet the legal requirements to serve in lieu of a U.S. visa when a visa is required. Travelers that possess a valid U.S. visa may travel to the United States on that visa for the purpose it was issued. Travelers traveling on valid visas are not required to apply for an ESTA. In the same way that a valid visa does not guarantee admission to the United States, an approved ESTA is not a guarantee of admission to the United States.
  • According to UCSIS, ESTA is an automated system used to determine the eligibility of visitors to travel to the United States under the Visa Waiver Program (VWP) and whether such travel poses any law enforcement or security risk. ESTA approval authorizes a traveler to board a carrier for travel to the United States under the VWP. Private carriers must be a signatory visa waiver program carrier. CBP recommends that you apply for ESTA at the time you book your travel, but no less than 72 hours prior to boarding.
  • ESTA became mandatory January 12, 2009. VWP applicants are required to complete a blue Customs declaration upon arrival in the U.S. whether or not they have an ESTA authorization. VWP travelers are no longer required to complete the green I-94W card.
  • Approved ESTA applications are valid for a period of two years, or until the passport expires, whichever comes first, and multiple trips to the United States without the traveler having to re-apply for another ESTA. When traveling to the U.S. with the approved ESTA, you may only stay for up to 90 days at a time - and there should be a reasonable amount of time between visits so that the CBP Officer does not think you are trying to live here. There is no set requirement for how long you must wait between visits.
  • Travelers whose ESTA applications are approved, but whose passports will expire in less than two years, will receive an ESTA valid until the passport's expiration date.

A Nonimmigrant Visa is a temporary immigration classification for a specific period of time. It is issued by a U.S. consulate or embassy, and permits a foreign national to enter the United States for a set, temporary period of time to take part in a specific activity. Examples of nonimmigrant visas include: B-1/B-2 Visitor Visas, H-1B “Specialty Occupation” Visas, L-1A
Multinational Executive/Manager Visas, TN “Professional” Visas for citizens of Canada and Mexico, E-3 visas for citizens of Australia, and F-1 Student Visas. 

Certain nonimmigrant visas, such as employment-based visas, require a U.S.-based employer tofirst file a nonimmigrant petition (Form I-129) with United States Citizenship and Immigration Services (USCIS). Once a petition is approved, the foreign national beneficiary can apply for the nonimmigrant visa at a U.S. consulate or embassy, or a change status if he or she is already residing in the U.S. in a valid immigration status.
