With the language barrier it would be difficult to make friends in an English/Spanish speaking city, although she would be there to work there would be little time or energy to socialise. I'm sure she would gravitate to girls from a similar background, but still she could just go back to Moscow, train with Eteri, family and friends are there. I'm not sure the Kazakhs are trying to break all of Soyfa's ties with Russia, just Plushenko -- who is a total mess basically that academy exists to create names for his and Yana's shows. The Kazakh officials were meeting with Eteri, they are definitely not rejecting Eteri. They could have done all that behind closed doors but actively promoted it.
And given what happened with a Canadian skater on US soil with a 6 year suspension handed out (should have been a life ban and arrest), as well as other similar scandals involving young females US soil, I think a young woman who does not understand the culture, does not speak the language, is extremely vulnerable. We see what happens to young women who speak English as a first language and understand the culture, and they still get taken advantage of. Unless there is someone there to chaperone her 24/7 I feel like leaving behind a culture and support network is very dangerous for her. She is still a child.
Let's look at the facts too, Eteri gets results with females. She knows what makes a female tick. I think she's honest, doesn't condescend, any criticism or demands come with the right intentions she just wants them to achieve their maximum because she can see what they are capable of, and the skaters respond.
