The ESTA Application Process
The Electronic System for Travel Authorisation (ESTA) is an online security and screening system operated by the U.S. Department of Homeland Security. When an ESTA is approved, it confirms that a traveller is authorised to board a flight to the United States under the Visa Waiver Programme.
The application is completed entirely online and replaces the paper forms that were once required on arrival. It also removes the need to visit a U.S. Embassy for a traditional visa, provided the traveller is from a Visa Waiver Programme country and meets all eligibility criteria. Submitting an ESTA allows U.S. authorities to review traveller information in advance, strengthening border security and helping to streamline entry procedures at U.S. airports.
⚠️ An ESTA must be obtained before travelling to the United States, regardless of whether the trip is for business or leisure.
How long is an ESTA valid?
An approved ESTA is valid for two years, or until the traveller’s passport expires — whichever comes first. Each visit may last up to 90 days, although travellers must not exceed 180 days in total per year.

Who needs an ESTA US Authorisation?
Travellers from any country participating in the Visa Waiver Program must obtain an approved ESTA before flying to the United States. It is recommended to submit the application at least 72 hours before departure, giving sufficient time for processing and for any issues to be resolved prior to travel.
When should I apply for an ESTA Authorisation?
It is best to apply as early as possible. Travellers are advised to submit their ESTA application at least three days before departure, and earlier if they can. Applying in advance ensures that, if any issues arise, there is still time to obtain a full U.S. visa from a U.S. Embassy or Consulate.
Why does the U.S. require an ESTA US?
The ESTA system was introduced by the U.S. Department of Homeland Security to strengthen border security. By receiving traveller information before a passenger boards their flight, U.S. authorities can carry out essential security checks in advance. This process not only enhances safety but also helps to speed up immigration procedures upon arrival.
What happens if my US ESTA application is denied?
If your ESTA is denied, do not travel. Airlines will not allow boarding without valid travel authorisation. In this situation, you must apply for a full U.S. visa through the U.S. Embassy or Consulate in your country of residence or citizenship.

What is the Visa Waiver Program VWP and how does it affect your travel to the US?
Before 2009, anyone travelling to the United States for business or leisure needed a passport with a full U.S. visa. With the introduction of the Visa Waiver Programme (VWP), eligible travellers from participating countries can now visit the United States using an approved ESTA travel authorisation instead. This digital authorisation removes the need for an Embassy appointment and makes the entry process far more convenient.
An ESTA is only issued when all eligibility requirements are met. Once approved, it allows the traveller to enter the United States without applying for a full visa, provided they comply with the conditions of the programme. Travellers from countries that are not part of the VWP must still apply for a conventional U.S. visa through an Embassy or Consulate.
How do I apply for the ESTA US Authorisation?
The ESTA application is completed online. Once submitted, applicants receive an email confirming whether their authorisation has been approved or denied. Most decisions are issued within minutes, although processing can take up to 48 hours.
You can submit your ESTA application directly through this website. If you do not receive a notification within 48 hours, please contact us so we can check the status of your application.

Does the US electronic system for travel document have an expiration period?
Yes. An ESTA is valid for two years from the date of approval, unless the traveller’s passport expires sooner. A new application is required if any of the following occur:
- Your name changes
- Your gender changes
- You receive a new passport
- Your country of citizenship changes
- Your eligibility status changes
What is an E-passport?
An e‑passport, also known as a biometric passport, is a standard passport book that contains an embedded electronic chip. This chip securely stores the same information printed in the passport, including a digital version of the holder’s photograph. An e‑passport is required for all travellers applying for ESTA under the Visa Waiver Programme.
