First things first: you cannot just show up with a winning smile and a dream. You need a valid passport, and it needs to be good for at least six months past your planned return date. Think of it like milk—check the expiration before you buy it.
Most visitors from friendly countries can use the Visa Waiver Program (ESTA). It’s an online application that costs about $21 and lasts for two years. Apply at least 72 hours before you fly, or you’ll be stuck playing the “What if?” game at the airport.
If your country isn’t on the waiver list? You need a tourist visa (B-2). This requires an interview at the U.S. embassy, which is roughly as fun as a root canal. Prepare your documents, be honest, and dress like you’re going to a job interview—no cargo shorts.
