Good afternoon. I have a brother who resides in Cuba and I want to know if from here in Miami I can do the paperwork for him for citizenship or if they have to do it in person. Cheers

If you are of legal age you must do it in person where you live, you need to demonstrate family ties with the father who is Spanish, but there are details that the consulate must see, check online the requirements you need, your brother can send an email explaining his case with details.

No.

I'm not sure but I think you should do it in Cuba
