Justice is supposed to be impartial, but it is not possible for immigration judges to truly be impartial, when rather than being independent judges, serving on the court as long as they exhibit "good behavior" they are, rather, instead, employees of the Department of Justice (DOJ), which means that they are employed by the same prosecutorial element that instigates immigration cases. This would strongly imply, in actuality, more than imply, that judges that are employees of the Department of Justice, will judge cases in the manner, more often than not, that upholds Department of Justice's goals in mind. That is not only inherently unfair to the immigrants that are being prosecuted in court, it in actuality, makes these courts appear to be nothing more than presenting a semblance of real justice.
Further to the point, this would indicate that it is basic federal policy to put forth that immigrants, by definition, do not have Constitutional rights, in particular, that the 14th Amendment, which states that no law shall "…deprive any person of life, liberty or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws," that this appears to be the mindset of the DOJ, signifying that justice will not and cannot be served.
The Attorney General of the United States is responsible for the appointment of Immigration judges, so it goes without saying, that the judges so appointed, are going to be in lockstep with DOJ desires, and if they are not, they will be replaced as necessary, because they are not independent, thereby their continued employment is at the discretion of the DOJ.
The United States likes to proclaim that it is a nation of laws, but when those laws are adjudicated in a court of law, in which one element, in this case, the prosecutorial element, has the judge in their pocket, than there will not be justice. Instead, what we receive in return, is whatever the current desires are of the DOJ, and the only thing preventing these policies from being enacted with no dissent, is the valiant defense made by immigration attorneys that at least make it difficult to enact Administration preferred immigration policies that often do not take into account the rule of law, nor due process of the law, nor equal protection of the law, but rather serve to circumvent such.
It is to the DOJ's convenience, to simply paint immigrants that do not appear to be legally within our country, as illegal, and thereby subject to deportation, without appropriate judicial review. The United States response to its current immigrant crisis, is basically an end around Constitutional law, which essentially allows the DOJ and its immigrant judges to determine whatever that they desire to determine in regards to immigrants, and further this purposeful and targeted discrimination, enables such immigrants to be more easily exploited by employers and other people in America, because those that have no rights, or limited rights, have little effective recourse when they are preyed upon, essentially creating a form of servitude and punishment without having been duly convicted, and thereby manufacturing in practice, a modern new form of subservience.
