Using AP after AOS interview

[Vox]

Hi there,

I have a valid AP and an interview for AOS coming up in a few weeks. I would like to leave USA and go on vacation two days after my interview.

Could I still use my AP to enter USA even if my AOS is approved?
Do they null a valid AP if you get approved during interview?

I would prefer not waiting for green carde to arrive which may take up to two motnhs.

Thanks,

Vox
