Is The US Gov.'s Policing Of The World Instead Of Its Own Borders To Our Detriment?

Well if it is the govt's policy then it started long before this current administration. I think companies have a right to have an employee prove their status as a legal resident or a citizen. After all I've just had to send my marriage certificate to my medical insurance company to prove that the person I have on my benefits is my husband. If companies had no choice than to just hire legal residents then people wouldn't try to come here for jobs that don't exist for them.
