There are two possible ways to stay long-term in Argentina – as a Permanent Resident or a Temporary Resident and it seems that it's not an easy and fast process, involving much paperwork:
Proof of identity: valid identity card or passport with at least 6 months remaining and a complete set of photocopies (including blank
pages).
Proof of entry: entrance stamp affixed to the country travel document or immigration card.
Birth certificate: translated to Spanish and legalized by the Argentine Consulate.
Criminal record certificate: issued by the country where the the last 5 (five) years were spent prior to entry.
Argentine criminal record certificate: Criminal record issued by the Argentine Federal Police (Azopardo 620. Buenos Aires).
Two color photos (4×4)
Employment contract: Signed employment contract from a business or place of work registered with the Argentine consulate. See the
department of immigration for more details/
Application fee: AR $600
All foreign language documents must be translated into Spanish by a
National Public Translator certified by the Association of Translators
(Corrientes 1834. Buenos Aires. Tel: 4373-7173). Original language
copies must be submitted along with their translations. The Department
of Immigration may request, if deemed necessary, additional
documentation.
As you don't work in Argentina, you can apply for Financier visa:
This is a broad-based and flexible visa and merely requires proof that
a guaranteed minimum monthly income of 8,500 Argentine pesos (ARS) or
2,200 USD can be paid into an Argentinean bank account. The
immigration authorities will require you to prove that this income
will continue once you have moved to Argentina. Income from
investments, annuities and dividends from a business are all
acceptable.
If you don't speak Spanish fluently, it's advisable to find someone to help you - an agency or at least a friend.
