Argentine citizens do not need a visa to enter the UAE, only the Argentine passport (valid for at least 6 more months at the time of travel), which enables a maximum stay of 90 days in the UAE.
Residents of Argentina who are not Argentine citizens might need to apply for a visa, based exclusively on the passport with which they will enter the UAE.
If the country that issued the passport has a visa waiver agreement with the UAE, then it is not necessary to apply for a visa.
On the contrary, if there is no agreement in force, then there is the need to apply for one.
