"Forcing green card applicants to leave will render many green card applicants’ ineligible because, when they leave the United States, they will trigger the 3- or 10-year bars on receiving an immigrant visa based on accrual of unlawful presence."

Note particularly the following:
> Asylees and asylum applicants: Generally, time while a bona fide asylum application is pending is not counted as unlawful presence.
So unless there's currently a huge backlog of people staying here illegally who are somehow eligible for green cards in spite of this fact, the government changing it's policies to require new applicants do so from overseas is not itself causing these applicants to violate immigration law.
> ICE was/is putting them in jail while they appear for immigration hearing at courts.

This policy change was just announced, and it has nothing to do with things that happened months ago.
