ESTA Terms

ESTA Terms

Application Number


After you have completed your ESTA application, you will get a number. This is your application number and you should make sure to write it down. You can use this number to log in over the ESTA website and check the status and validity of your application.

B1 / B2 Visa


B visas are non-immigrant visas for the USA that allow the holder to enter the USA for tourism or business purposes for a total of 180 days. It is usually issued for 10 years.

Applying for a B visa is very time and cost intensive.

Biometric Passport


You are required to have a biometric passport when applying for an ESTA. These new passports have chips in them and are, therefore, machine-readable. 

ESTA Country


There is a list of countries deemed as low-security and whose citizens are eligible to apply for ESTA under the Visa Waiver Program. These citizens are eligible to apply for an ESTA and travel to the USA visa-free.

ESTA Status


After submitting your application online, you can check the status of your ESTA by logging in online. There are three different notifications:

Global Entry Program


Global Entry is an expediated entry program operated by the U.S. Customs and Border Protection. It allows low-risked, biometrically registered travelers to cross the US border more quickly.

Issuing Country


In your ESTA application, you must give the issuing country of your passport. This country should always be identical to the country of your citizenship. For example; despite your Italian passport being issued outside of the country, it was still processed by the Italian consulate.

National Identification Number


Every country in the European Economic Area is assigned a code so that every citizen can be easily identified. It can either be a tax number, social insurance number, or a personal identification number – the code differs from country to country which is why your national identification number depends on your citizenship.

Not all countries in the Visa Waiver Program are required to give a national identification number when apply for an ESTA. 



The term overstay is assigned to people who stay in the USA longer than their travel authorization or visa allows. An overstay can lead to negative consequences when trying to reenter the United States or applying for a US visa later.

Passport Number


Your ESTA is in directly connected to your passport and that is why it is required to give your passport number when applying to travel visa-free to the USA with an ESTA. You will find your passport number in the upper right-hand corner of your passport. It usually consists of both letters and numbers. Make sure that you do not confuse the letter “O” with the number “0”.

Visa Waiver Program


The Visa Waiver Program allows citizens from certain low-risk countries to travel visa-free to the USA for stays of up to 90 days.
