Advance Parole

I actually had AP before I applied 5 years ago through DACA because my grandma was sick so I did it under humanitarian. I got discouraged and never went because my mom consulted someone from an agency and said it was not safe so the $ I paid and everything went to waste. This time I have a i130 approved and I mailed my i485 two weeks ago and just waiting for the notice of action letter. I did not mail the i131 AP along side with the i485 because I did not think about it originally I was just happy I had all my evidence and documents ready to do i485. Question on the AP application, is it specific to ONE country? and there is also a question on there if you want this as a single entry or multiple, not sure which one to put. What did you guys do? also, if anyone had a AP approved already, can you post your timeline? thank you .
