ESTA Requirements:
It is necessary to meet the ESTA's standards in order to obtain it. If you meet the following criteria, you may apply for ESTA Visa easily:

You must be a citizen of one of the 40 countries that participate in the Visa Waiver Program.
You have a plan to stay in the United States only for 90 days.
You do not have a valid visitor visa to the United States (B-1 visa or B-2 visa).
You should clarify that your tour to the US either is for pleasure or for a business purpose.

If you don't follow any of these instructions, it is difficult for you to take USA Visa.
Apply For ESTA Visa:
The first thing to keep in mind is that your ESTA application must be submitted at least 72 hours before your trip. Remember, even if you're changing aircraft in America, you'll require an ESTA. What you need to do is apply for an ESTA visa online at the official ESTA website.

It is important to keep in mind the application number so that it may be easy for you to monitor the progress of your ESTA status or make changes to your information. You can pay your ESTA payment through the ESTA website. Otherwise, you will face difficulties in paying high charges as well.
How Many Times Can I Enter The USA With An ESTA?
You are allowed to enter the United States many times and stay for the whole 90-days period. However, you must avoid making frequent visits to get rid of questions about whether you are genuinely residing in the USA or not. So, if you fly to the United States for 90 days and then return after 10 days, Customs and Border Protection authorities will be suspicious and may refuse your entry. There is no set number of days that you must wait before returning to the United States, however, it is recommended that you wait for a reasonable amount of time.
Last Words:
ESTA is a US-created online portal. The goal of this website is to help you apply for a USA online visa. If you apply through the official website, you will not have to pay a single penny as an additional fee. As well, it will keep you away from visiting embassies again and again.
