Yes, they're two different groups. If you are coming for training, TSA may or may not have to approve you to get training. Like I said, if you are adding a skill set. ICE also gets involved if you are coming as a student and need a student visa or if you need a visa as a tourist. If you have a FAA cert and are just a tourist from a non visa courty who may be flying a plane I don't know if ICE cares.
