I have a question regarding naturalization "por opcion". I have a "residencia no lucrativa" and I am a Brazilian citizen. I would like to naturalize "por residencia" after two years of residency in Spain. Once I naturalize, can my child automatically become a Spanish citizen? I know "por opcion" is possible if you have Spanish parents. However, in this case, at the time of the child's birth, I was not Spanish. I only would have become Spanish AFTER the child's birth. Can the child still get nationality "por opcion"? The child was born in Spain and had a NIE, but the NIE expired and the child no longer has a NIE.

Thank you.
