Marcel,
There are numerous ways to get a US visa, but unless you have a family member here or are planning to study full time, it can be complicated.
Like Johan says, the *best* thing for you to do is apply for the US Diversity Visa Lottery. It is free to enter, and it is easy. Last year 94 Dutch citizens won this lottery.
The US Government's Diversity Visa Lottery (also known as the 'Green Card' Lottery) is now underway -- you can apply *only* between 1 November t/m 30 December this year. Starting this year, you can apply only online and you must upload a suitable passport photo accrding to strict USCIS format requirements.
Good luck,
Dick
