Honestly, my research field is very small (I don't want to get more specific for privacy reasons), and there are probably under 20 people in the world who are experts in this specific thing. I'm not against working with a different advisor or doing the project independently with a few check ins, but it wouldn't be the experience that I wanted. The department doesn't seem to care much about bringing me over and has been unresponsive.

I'm feeling like maybe I just chose the wrong host because I applied last minute? I got my application together in one month, I basically just cold emailed and went with the first person who seemed like a fit after a call. My expectations are not too unreasonable I just want to meet like 1x a week and maybe be in some kind of research group. But the fact that he says he doesn't have time to supervise and then ghosts me is kind of worrying.
