Hi jarajaramelon, well birthday coming up........so happy birthday in advance!!
And I go along with you can invite whoever you want to your party!!
Although please don't be disappointed if they aren't able to come, there may be protocols in place which mean that they aren't able to.
But........very nice thought from you to invite them, so just go ahead and see what happens (even if it only results in them being flattered that you'd invite them ).
