Wow im suprised (not really) the illegals are not deported immediately. Why are illegals not deported immediately?? Dont make sence. THERE ILLEGAL!!! Last I heard there breaking the law. So the next time I do something illegal like speeding then I will call it bias to ticket me but not enforce immergreation laws!
If they have a prior deportation
vis-a-vis an ICE 'A' number in CIS, then they
are expeditiously repatriated to their home country often via
JPATS. Not pretty but that side of the system does work pretty well. When they are sent back, they are tracked in ENFORCE/
EARM (formerly DACS) which expedites subsequent deportations.
If an ICE, CBPO or Border Patrol Agent locates you in CIS or ENFORCE/EARM with an A number- you are going home in a very expeditious manner one way or another. Deportation/removals do show up on III raps and all the identifiers used by local le is capurted in ENFORCE/EARM - FBI/SID numbers etc. SO it is really quite easy to develop this information if one just looks for it.
However, no prior deportation then then it becomes complicated if the illegal does not agree to VR (voluntarily return) and leave the US. If they fight it becomes a typical criminal justice meat grinder with a criminal charge, due process, bonds and attorneys and this can take years between the defendants immigration attorney and the system itself.
If there is not a violent felony or dope involved these are a little more challenging to get charged. ICE wants the Violence and Dope more than anything else (who can blame them).
So to assure you that part of the system works well for the most part, the other part is burdened with all that due process civil rights mumbo-jumbo that people love to hate the USA so much for.
