I had a petition done for me and it took about 13 years to become current. It wasn't fun watching the dates because sometimes it would go really fast - skipping 2 or 3 months at a time then it would slow down to 2 weeks and a couple of times, it even jumped back 2 years in a "retrogression".
Should you do it? I say absolutely. You don't know what will happen in the future. When I got mine, I would have laughed if someone said I couldn't find a way to get legal in 13 years, but here I am.
In my case , I haven't gone through with adjusting of status though because the current government has made it clear that anybody with an existing final order is a target and I don't want to go into a building without knowing I can walk back out. In 13 years, you never know.
