Apply green card for my mom

That's because I don't see threads with anybody inside the US with an H or L visa who has said they are about to choose consular processing. The vast majority file AOS. Of the few threads I have seen where they chose CP, they had already requested CP months or years ago and they're close to having their consular interview or already did the consular interview, so there would be no point in suggesting AOS at that stage.

It's also worth remembering that most H/L holders are employer-sponsored, and AOS gives them AC21 benefits, which CP does not. That's a huge advantage, especially in uncertain economic times.

CP used to be a lot more popular among EB aliens prior to December 2000, when AC21 was passed. At a time when most PDs were Current and you weren't able to port the application to a new sponsor, there was tremendous advantage in concluding the process as quickly as possible.

Indeed.

I bet that Triple Citizen would ask the same.
