You might need a competente lawyer to help you apply at the Federal Court.As I don't have a temporary or permanent residence nor DNI, I cannot apply online through migraciones/RaDEX.
I'm planning on getting married in the next few months. Would it be possible to apply in person after marriage without DNI?
Some of them like mine suggest Federal Court has already closed it's door for citizenship,
but one lawyer here at least can confirm Federal Court is still accepts citizenship application, so...
