Advance Parole

Hi guys. I just wanna ask a question . I have been waiting for my interview almost 17 months but after that Wich was in October 2019 and my PD Is may 2018. I didn't get any answer after the interview just a white paper saying to wait for 120 days for a decision. So I decided I wanna renew my EAD and apply this time for Advance parole Wich I didn't apply before. The first time I only apple for my EAD because I thought my GC wouldn't take me this long. But I am tired of waiting because I miss my family. I married a UC , family based
So I am planing to travel on March. I just send my papers today morning.
Do you know how long does it takes to renew EAD and get advance parole as well?
The first time it took 4 months. So I am worries how long it is gonna take now.
And do you of anybody who got denied i485 while was outside of US waiting for an answer and couldnt reentry to US ?
God's willing I am just praying and thinking positive but doesn't hurt to ask that. Thank you for your help.
I am planing to reentry San Francisco airport.
