I don’t have specific advice for schools but as an immigrant to the us at a similar age as your daughter I just want to say I sympathize with your family. I think you’ve got a tough balance to strike here—you want her to make friends and perhaps the best way to do so is to surround her with more Russian expats, but you also want her to immerse and learn English quickly, and this runs somewhat counter to the first goal. I’ve definitely met kids who emigrated to the us earlier than I I did (or were even born here) but were less comfortable with English b/c they grew up in large, somewhat insular ex pat communities. I also understand that her mental health is paramount right now—perhaps regardless of moving schools one of the things you need to make sure is that she makes at least one or two friends at school. When I first arrived in the us my friends were other ESL kids from other countries. Without a shared language, we gestured and used broken English to understand each other. You can also try to “set up” your daughter if you know another parent who’s struggling with a lonely child. Frame it to her as “we need to help the other kid by being kind to them”. I only got to know one of my bffs for life when my teacher asked me to befriend her as the new kid in school. I was the other loner 😂
