The previews in Boruto tend to be misleading and display as little information as possible, but I can't imagine any reason Sai would be investigating academies in other Shinobi villages if it wasn't to transfer Sumire. I think the writers believe Sumire has to disappear from the scene for at least a few years to give Sarada a chance to be the female protagonist she is supposed to be and develop some sort of relationship with Boruto. I mean, look at the very different way Boruto treats Sarada and Sumire! just like how Sarada asked Boruto if he wanted to be Hokage because she must have tought that if he did she could kiss goodbye her dream of being Hokage one day, if Sumire stays Sarada could kiss goodbye the possibility of ever having an opportunity with Boruto. I mean, I think having a family of sorts by becoming Sai's protegee even if she is banned from becoming a ninja (since she clearly isn't ANBU material either) should be closer to what she would want for herself than having to start from scratch all alone in another ninja academy in another village far away.
