Dutch nationality can be obtained through naturalisation or the option procedure.
For naturalisation, you must have had a valid residence permit for at least five years without interruption. You must also have passed the civic integration exam. Depending on the nature of your current residence permit, there may be the additional condition that you must proof your identity with an authenticated birth certificate and passport from your country of origin.
Dutch nationality may also be obtained through the option procedure. Unlike naturalisation, this does not force you to renounce your own nationality.
In most cases, this requires a long-term stay in the Netherlands, and a certain family connection to a Dutch national. The conditions are set out on the IND website.
If your application is rejected, I can lodge an objection with the IND on your behalf.
