Different specialty, but I’m applying radiology and there are quite a few people I’ve met that are applying without completing their first residency. Although they never said, I assume they were terminated or “resigned” since they were former surgery residents. They still interviewed at good places. I assume that as long as your app is good, you have a good story why you didn’t finish, and don’t have visa issues, you’ll be okay. While there may be some funding issues, from what I understand they can still find funding, just makes it more difficult.
