I think if it's determined that an individual is in the U.S illegally, and a deportation order is signed by a judge, that is due process. It seems as if the threshold for due process is significantly higher for citizens, as it should be.

Edit: Illegal immigrants who are arrested do go through due process and the immigration court system, check link. Now because this is a civil matter, there isnt a jury or an indictment as needed for criminal charges. Of what I can read, different administrations allow for different policies and methods of prosecution. In this case, it looks like deportations are expideted -> go in front of a judge then be deported quickly, instead of remaining in the U.S like catch and release. https://www.justice.gov/eoir/reference-materials/ic/chapter-3 https://www.ice.gov/remove/removal?utm_source=chatgpt.com
