A person who has 2 years of legal residency in Peru, be it by marriage or other reasons such as work, can apply for naturalization. The 2 year requirement starts from the date one acquires residency in the country, provided that residency never lapses. The years must be consecutive. If a person has a work visa that expires, and renews it later, it doesn’t count as two consecutive years. The renewal must happen before the expiration of the first. For married people, simply staying in the country is sufficient.
The person does not lose their previous citizenship, no letter of resignation of it is required. Unless acquiring citizenship in Peru would conflict with the former country’s laws, such as for Japanese Citizens.
