Question about Infantry Training Procedure after graduation.?

I finally got the letter with the actual Company in it for my boyfriends BCT. I looked up his graduation date and it's July 10th. He started April 3rd officially but been gone since March 23rd. What happens after BCT graduation? He doesn't go to AIT since he's Infantry, is that correct? Does he come home then? Details would be great....do they get to come home that day of graduation? His reservation paper said 13 weeks and 6 days. That would be April 3rd to July 9th. So he's done after that? This stuff confuses me!
