I guess they mean “in the country illegally” but I presume you could also argue that if they entered intending to overstay the visa, they entered illegally.

Yeah something like that. Of the people who entered the country that year and who were now in the country illegally, 2/3 had entered on a valid visa.

Was trying to figure out a succinct way to say that and instead just butchered it. Words are hard.
