If I suspect that one of my colleagues is undocumented, how can I report them to immigration authorities without getting in trouble? 
I'm concerned about the legal implications of reporting a colleague, as well as the potential impact on their life. Is there a way to do this responsibly and respectfully?

As an employee, you do not have the legal authority or responsibility to report a co-worker to immigration authorities. Under no circumstances should you take any steps in the direction of reporting them without consulting with immigration experts as it could be seen as retaliation and illegal. If your concern is for the safety and wellbeing of your colleague, you may want to consider reaching out to a trusted contact at an immigrant advocacy organization who can provide guidance on how best to handle this situation while respecting the privacy and safety of your colleague.

You should be aware that reporting someone to immigration authorities without their consent can have serious legal repercussions for both you and the person being reported. It is important to keep in mind that someone’s immigration status does not make them any less valuable or worthy of respect than someone who is documented, and thus it is important to use caution when considering whether or not to report them. It may be prudent to consider reaching out and verifying facts with an immigration professional before taking action, if possible. This will help minimize possible conflicts arising from mistaken identification of a person's immigration status while providing useful guidance for future reference.
