Do you mean the NT2 exam or NT2 classes?
For the Staatsexamen NT2, you have to go the Netherlands. You may be able to find Dutch classes in your area to prepare for the exam. Maybe you are confusing the NT2 exam with the 'Inburgeringsexamen' that people need in order to apply for a Dutch residence permit. See this thread (among others) for more information: viewtopic.php?f=51&t=1431
. EU citizens do not need to pass this exam.
