While they could do it illegally, the case you have to fund yourself is a civil case against the government to decide whether your naturalization can be removed. Only once it is removed can they deport you as a criminal per the supreme courts ruling. Every person deported prior to the civil court case would be a “fiasco.”. Not saying it won’t happen, but the Supreme Court so far deems it illegal.

Unless I missed something, where did you see that ruling?
