What paperwork is required for an expatriate to register residency here?

Expatriates relocating to San Martín de los Andes must first obtain a temporary residence visa from the national immigration authority, which typically requires a valid passport, proof of income or employment, and a clean criminal record. Once in Argentina, you register at the local municipal office to obtain a local identification card (DNI) and a tax identification number (CUIL). You’ll also need to enroll in the national health system, which may involve presenting your visa and proof of address. Detailed instructions, required forms and processing times are published on the federal immigration website and the city’s official portal.
