Ya its a bummer you can only use it in Belgium and some small countries in the Carribbean haha!
Ive been here almost 3 years and i can tell you; everybody in NL speaks English. Most of them speak it very well. I've met people who have been here 10+ years and dont speak the language.
That being said, I plan on staying here for the considerable future, its not out of the question that i decide to settle here too, so I do think its important to speak the language.
