Here are just some of the documents you will need to apply for Peruvian citizenship (because of marriage):

• SOLICITO: NACIONALIZACIÓN DE PERUANO(A) POR MATRIMONIO;
• DECLARACIÓN JURADA DE CONVIVENCIA;
• GOZAR DE BUENA SALUD, NO PADECER ENFERMEDADES;
• Form F-006;
• To prove your family income they asked for 3 months of pay stubs.

Using Adobe Acrobat Reader you can fill the documents and save them… in case you have to go back again.  I’m going back on Thursday; I’ll let you know how it goes in this year of good service.
