Whenever USCIS stakeholders meeting takes place, a comment should be sent to keep F4 category cases pending as long as they can may be until priority date becomes then they should approve it, so that it knocks off time & help this kind of cases.
You still seem to be missing the point. The point of CSPA is to ensure that any inefficiency on the part of USCIS does not penalize derivatives. It is not to intentionally make uscis more inefficient to “help“ those who would age out. The more people “helped” in the way you envisage will just increase overall backlogs and make things worse for everyone, including the immediate relatives who have a visa number immediately available yet still have to wait a year or so to actually immigrate because of processing times.
The second point you miss is that the reason there is an age limit on the immigration law definition of “child” is so that famiiies don’t have to leave kids too young to look after themselves behind.
For example: F4 for phillipines has approximately a 23 year wait. I’d find it hard to see how, from an immigration priority perspective, uscis should delay processing these cases for 23 years so that a bunch of 40-somethings get the chance to piggyback immigration because they’re ....too young to be separated from their parents?! I’m not sure if you aware either, that there is a numerical limit on F-categories each year. So the more older “children” that come in this way would reduce the number of slots available for later F4 cases, again making the backlog even worse.
....it would just be easier to abolish the age limit on what counts as a child - as that is effectively what you’re proposing by wanting CSPA to protect everyone forever. Obviously that’s not going to happen.
