Hi beautiful/handsome people on this thread

I got my AOR on Jan 28 and my estimated completion date is Feb 28, 2022. I’ve been advised by some of you nice people here to do upfront med, my question is how can I do it? Please can someone enlighten me. Thank you! Also, i am an inland applicant and i got my bio in 2018 which i can see in my GCKEY account that it’s valid until 2028. Do i still need to do bio in this case? I don’t have any sponsor too so i guess I don’t need PAL? Any comments/recommendations are highly appreciated. Thank you!!!
