I'm moving down there in two weeks. I don't have a job lined up yet, but I want to have all of my paperwork in order should I need to apply for a DNI. My question is this: I understand that the FBI criminal background check is basically void if you get it prior to your departure from the states. Should I get my background check the day before I leave, or should I wait until I arrive in Argentina before I get it? I don't want to go through the hassle only to find that it is worthless since I haven't left quite yet. I appreciate any feedback. Thanks.
