Thanks! We need to go into details here. Where do you have Orthodox churches in Argentina? Any Romanian orthodox church by chance, anywhere?
There is a splendid Russian Orthodox cathedral in Buenos Aires, famously built in 1900 and situated near the quiet Lezama park.
There's also a beautiful Russian Orthodox cathedral in the wealthy Buenos Aires 'Palermo' neighbourhood, and this church was cowardly vandalised (tagged) at night by agents of Zelensky last year. But, good thing is, the dignified Argentine authorities officially and vehemently condemned this despicable attack on a holy place. This church is now protected, no further trouble has been reported. Most Russian newcoming families settle near this cathedral, I've noted.

In any case, in the best maternities of Buenos Aires, they now have documents in Russian language available at the check-in office. I noticed this about 6 months before the Guardian and La Nacion MSM did... Also, ten percent of new customers at my bank are Russian families, coming from many cities throughout the Russian Federation.
Regarding the Romanian community, I'm not sure, though I think they go to a small (Serbian or Romanian) Orthodox church situated between the Garrahan and Británico hospitals. Also, note that in Buenos Aires, I've seen a good number of Oriental Catholic churches for Armenians and even Libaneses or Coptics.
