I doubt foreigners got here (likely on a work visa) with no skills or education. To get a work visa, don’t you have to have a job lined up? There’s their experience/skills. Myself and a lot of the class I graduated with in CS are getting hundreds of rejections despite having relevant education (and experience in many cases). With the hundreds of thousands laid off from tech in the last year there is absolutely not enough openings for everyone with skills and relevant education.
