What is the difference between an US Visa Online (or ESTA) and the normal US Visa

Before we tell you the difference between a US Visa and an ESTA US Visa (US Visa Online), let us brief you on what these two terms stand for. A Visa is primarily a temporary and conditional authorization given by a governing polity to any foreigner who wishes to travel to different territories/countries and this Visa permits them to rightfully enter, remain within, or exit the territory/country in question.

The US Visa that is given to such travelers has certain parameters that hold dominance over their stay in United States. For example, the duration of their stay, the areas that are permitted to visit within that USA, the dates they are expected to enter, the number of visits they make into USA in a specific period or if the person is capable enough to work in the USA for which the visa is issued.

US Visas are basically permission slips allowing one to enter and stay in United States and every country has its own set of instructions given to allow any person to traverse to another country or territory. You will have to visit the embassy to apply for USA Visa.

ESTA stands for Electronic System for Travel Authorization. As the name suggests, it is an automated system that verifies the eligibility of travelers for travelling to the United States under the governance of the Visa Waiver Program (VWP).

When a person gets authorised by ESTA Visa USA (or US Visa Online), it does not decide whether the visitor is admissible to the United States of America. The admissibility of this visitor is only determined by the US Customs and Border Protection (C.B.P) officers upon the visitor’s arrival to the place. There are certain rules to apply for USA Visa online as well.

The purpose of the US Visa Online Application is to collect biographic details and answers to Visa Waiver Program eligibility questions. This application is required to be submitted at least 72 hours before the travel date. Although it is advised that the visitor applies as soon as they plan to make the trip or before they set out to purchase the airline tickets. This buys them ample time to avoid any kind of glitch which might occur during the process of application. Then they will have time in their hand to correct any mistakes that occur.

Difference between a Visa and an ESTA

A Visa is different from an authorised travel approval and they are not the same. It does serve the function of the legal or regulatory requirements with interest to the United States visa in a scenario where a visa is the only mandatory requirement that is recognised by the United States law. The visitors who carry a valid USA visa will be allowed to travel to the United States based on the validity of that visa and the purpose for which it was issued.

Those who are travelling with valid US Visa do not need any other kind of travel authorisation to traverse to the United States. A travelling visa will specify the purpose of the visit, given the traveler solely travels for the respective visa. So according to your purpose of visit apply for USA Visa.

What is ESTA (or US Visa Online) and when is it required?

To further the existing security of tour and travel in the United States of America under the Visa Waiver Program the immediacy to travel without a Visa has been enhanced.

The passport holders of Visa Waiver Program countries are still eligible enough to travel without having to carry a visa but at the same time, they are required to get their travel authorisation approved, 72 hours before their visit to the United States. This authorisation is called ESTA ( or US Visa Online). To apply for USA Visa online is quite smoother than the traditional one.

As soon as you get to the required biographic details of US Visa Application and payment information provided on the website, know that your application is now under process by the system to check for your eligibility to travel to the United States under the Visa Waiver Program without having to carry a visa with you. An automated response is generated by the system in which you have applied to and right before your boarding, a carrier will verify with the United States Customs and Border Protection electronically that your approval for travel authorisation exists.

The applicants who get approval should know that ESTA Visa USA or US Visa Online is only valid for two years or till the time their passport expires, whichever happens first. When you plan your travel to the USA, know that you can stay for upto 90 days on a single trip.

Also note, to apply for USA Visa, a fresh authorization of ESTA is needed if any of the following happens:

If you get issued a new passport.
You decide to change your name (first or last)
You decide to redefine your gender.
Your citizenship changes.

Why is ESTA or US Visa Online compulsory?

The “Implementing Recommendations of the 9/11 Commission Act of 2007” (9/11 Act) made an amendment in section 217 belonging to the Immigration and Nationality Act (INA), which requires that the Department of Homeland Security (DHS) puts into force an electronic travel authorization system and initiate other required measures to strengthen the security of the Visa Waiver Program (VWP).

ESTA only acts as an added shield serving as another layer of security that permits DHS to analyse before the travel, whether the traveller is eligible to travel to the United States under the requirements of the Visa Waiver Program and whether or not such travel hints at any law enforcement or security risk.
