There is significant political support for effectively open borders, which has the effect of importing unskilled labor without the permit implied by a guest worker program.
I'm not arguing these are good or bad (H1Bs especially are abused) but they definitely happened and have a massive groundswell of support from one party.
You think they’re going to try to lobby to get blue collar people in? “Effectively open borders”, my ass.
That said, if the general case folk get their way, I assume that your special case will be included.
I do note that folks who want lots of low-skilled immigrants (the "who's going to pick grapes" folks) might not care that much about every instance of high-skilled immigrants.
