What do you mean by "these days"? My wife and I have done h1 porting 3 times in total during the pandemic (once during President Trump, others during President Biden), and the process was insanely fast (== 1.5 month total from starting email with lawyer to I797 in hand, including a week at DOL and about a week at USCIS for the I797). We used Premium Processing (never not used it, except during the time it was suspended a few years ago).
I was curious if it has ballooned back up since May 2021.
