5000JD is ENTIRELY too expensive. Keep in mind, since you are a foreigner, you will be gipped quite a bit (Im sure you know people in countries with lesser economies always try to pilfer the money out of the pockets of foreigners they perceive to be from "rich" countries; how the world works, isn't it?) I don't have a lawyer for what I'm doing, but my husband is one so maybe I'm out of the loop
Getting naturalized takes years of course, just like any other country, but citizenship is alot faster I hear. Im told I have to renew it yearly.
