Not to worry gentle companion. If you're a from one of the 38 countries listed here, you can travel to the USA without a visa.
Instead of a visa, you can use ESTA. ESTA stands for the Electronic System for Travel Authorization and it allows citizens of the aforementioned countries to travel to the USA under the Visa Waiver Programme (VWP).
Applying for an ESTA Visa
Applying for an ESTA Visa is easy, all you need is an electronic passport and internet connection - that's right, there is only one form to complete and it's all online - the ESTA application takes around 30 minutes to complete, and your ESTA can be approved within seconds of application.
The ESTA sounds too good to be true? Right?! I hear you. But, wait! There's more... Unlike a visa, an ESTA lasts for two whole years. That is, of course, unless your passport expires within that two year period.
In that two year period, you may travel to the USA as often as you please. Please note, you must have a return flight booked every time that you fly to the USA.
You cannot use ESTA to work or study in the USA for that you would need to apply for a visa.
Finally, an ESTA costs $14, that's it. Compare that to a visa, you can probably multiply that figure by at least 10.
To apply for your ESTA, you can use the official government website.
