If you think you might be moving to Amsterdam soon, there are a few preparations that you should make. Think about whether you would like to try to learn the local language before you go. Most people in the city will speak Dutch as their native language. English is extensively taught in the local schools here, so you may be able to find many people to talk to you. Keep in mind that they will be appreciative of anyone who makes an effort at learning their own language.
You should also work on getting a visa to the country sometime soon. This process may run much more smoothly if you hold an advanced degree from your country of origin. Think about filing the paperwork early on during your move, so you can advance the application process somewhat. The Netherlands are a member of the Schengen Agreement, meaning that other European residents can freely move within its borders. This may be helpful if you are already a dual resident.
It is important to realize that Amsterdam is a large city, so you may want to get familiar with the street grid and metro network. There are quite a few different types of apartments and homes available here. Consider getting a condo in a townhouse unit that overlooks one of the many canals in the city. The country currently uses the Euro as its primary currency, so you may want to start exchanging for that. There are quite a few jobs available in the retail and fashion industries within the city.
One final thing to consider is the amount of things you will be bringing with you. Consider enlisting the help of an international mover. An international mover will be able to bring all your things from door-to-door, as well as advise you on getting visas and where to go once you are in Amsterdam.
