I didn't apply for permanent residence in Peru. Can I apply later?

Of course. According to Peru's national policy, anyone who has legal residence in Peru for two years can apply for naturalization, and those who do not want to be naturalized can apply for permanent residence after three years of legal residence. Their previous residence in the country is recorded, so they can apply later. Permanent residency refers to the right of an individual to stay permanently in a place with permission, but he does not necessarily enjoy civil rights. People with permanent residency are called "permanent residents".
