If you're a European resident you're in the Visa Waiver program which means you don't need a visa for any visit of your stay is less then 90 days.

Thank you for your advices ! Unfortunately, my country, even though is part of the EU for 10 years now, has not been inclued yet in the visa waiver program, which means that I have to apply for a visa anyway.
