I had a bench warrant for a dui from 10 yrs ago and have lived a clean life since then until bench warrant picked me up ,while at bench warrant immigration came and spoke to me and when they took me to the correction facility there was an ice detainer on me but when I paid my bail the detainer was lifted ,why was this? And does this mean I have to leave the us anyway
