The United States has updated its visa policy for increased security. As a result, it now takes longer to obtain a visa. Advance planning by travelers is essential to avoid frustration and disappointment.
The Visa Waiver Program (VWP) enables most citizens or nationals of participating countries to travel to the United States for tourism or business for stays of 90 days or less without obtaining a visa. Travelers must have a valid Electronic System for Travel Authorization (ESTA) approval prior to travel and meet all requirements explained on the US State Department Visa Waiver Program website. If you prefer to have a visa in your passport, you may still apply for a visitor (B) visa.
Currently, 38 countries participate in the Visa Waiver Program, as shown below (taken from the US State Department Visa Waiver Program website):

A passport with a validity date of at least six months beyond the applicant’s intended period of stay in the U.S. is required. If more than one person is included in the passport, each person desiring a visa must make a separate application. Please check with the website, https://www.cbp.gov, to confirm that your passport is compliant. Temporary Passports will likely merit special scrutiny. To avoid complications, check with your local US consular offices, well ahead of your intended departure dates.
A visa support letter can be provided for authors and registered attendees upon request. To allow sufficient time for processing, please submit your requests for letters of support well in advance of your interview dates.
