Putting in leave after tech school

I know i probably shouldn’t be worried about this right now cause it’s such a long way away, but I’m supposed to graduate May 6th from tech school and once I get to my first duty station, I want to put in leave immediately for July (only for two days) theres an event I want to go to that’s very important to me back at home and I don’t want to miss it.

Service before self of course…but would that possible? I understand I need to discuss that to my leadership but how likely are they let me have these days off? Would it be too soon?
