I want to apply for a Dutch passport but I am not sure if I qualify. I was born in 1967 in SA after my mom moved to South Africa and married a South African man. My mom was born in Haarlem in 1944. She never renewed her Dutch passport when she moved to Sout Africa and got married. Do I qualify?
As @phoog said in the comments, if you were born before 1 January 1985 to a Dutch mother and a non-Dutch father, you can apply for Dutch nationality via an option statement. You can find all the requirements here. It's laid out quite clearly by the Dutch government. You can submit your application in person at the Dutch embassy or consulate-general in the region where you live.
