As a Spanish passport holder, planning a trip to the United States is actually much simpler than you might imagine. Having recently completed the entire application process myself, I’d like to share my experience with you.
ESTA Electronic Travel Authorization System
Spain is a member of the US Visa Waiver Program, which means we don’t need to apply for a traditional tourist visa. We simply need to apply for electronic travel authorization through the Spanish US visa application ESTA system. The entire process is completed online, and you typically receive results within 24-72 hours. ESTA is valid for 2 years or until your passport expires, whichever comes first.

The documents needed for ESTA application are quite simple, mainly including a valid Spanish passport, a credit card for payment, and some basic travel information. The fee is , and I recommend applying directly through the official website esta.cbp.dhs.gov to avoid additional charges from third-party websites.
Application Process and Timeline
| Step | Required Time | Important Notes |
| Complete online application | 15-30 minutes | Ensure all information is accurate |
| Payment processing | Immediate | Only accepts credit or debit cards |
| Await approval results | 24-72 hours | Recommend applying at least 72 hours in advance |
When filling out the application form, pay special attention to the accuracy of personal information, including passport number and date of birth. Any incorrect information could lead to US visa application rejection. Additionally, regarding travel plan questions, even if you haven’t confirmed specific hotels or itineraries, you can provide approximate information that can be updated later.
Important Considerations for US Entry
Once you receive ESTA authorization, you can stay in the US for up to 90 days per visit, with no possibility of extension. It’s important to note that ESTA doesn’t guarantee entry - the final decision rests with border control officers. I recommend preparing return flight tickets, hotel booking confirmations, and other supporting documents for potential inspection.
Special reminder: If you’ve previously been denied a US visa or have any criminal record, consider consulting professionals about whether you need to apply for a traditional B1/B2 visa instead of using ESTA.
