if you are looking for his A number (alien number) call the INS/ICE location where you think he may have been processed. Talk to the detention and deportation branches (both, one tends to pick up more than the other but you will get it eventually). You didn't give really any info so I don't know if this is what you want....specifics....you can you the A # to locate where a detained undocumented immigration is being detained, if they have a court date set up ,etc... there is an automated system, at least in Texas that you call and plug the number into... once again, more details???
