Can my 16 year old son with F2 visa enter US 1 week before me, his F1 visa parent?

If this is the first time that the F1/F2 visas will be used, your son cannot enter the US before you as you are the principal F1. If you had already entered the US using the F1 previously, and were just outside the US on a trip, he could enter before you – but the rules for first-time use dictate that you must enter first or you can both enter together, but he cannot go first.
