what must do a russian women to travel to Argentina?

whta kind of conditions? what kind of visa?

I think that Russian citizens must apply for a visa BEFORE travelling to Argentina, whether as a tourist or for business.
You can contact the Argentina embassy in Moscow for more information:
Rusia, Codigo Postal 119017 Moscu, B. Ordynka, 72
