Well, I think CHOR put it nicely.

Make sure that you actually have proof about this. Bhutanese are folks who are very scared of authorities even when they have the right. We have been conditioned to be such, and we ain't very proud of that.

Things slip out, unintentional things happen.

"Did you try that gas station?"

"yes, I did, but there is already a Nepali guy working there?"

"Can he help you find a job?"

"No, he is also a student working part time. He can't help me."

And that would do it.

So, please make sure that this simple incident does not lead to a flaring of conflict between us.

I also do think (or rather know) that US authorities are very aware of the students in various status working illegally. They don't persue because it is not worth it. Why would this one incident make them spend time on it? 12 million illegal people work in this country, and the authorities know. If anything, postings in public forums like it could just invite investigations than complaints from a dude fresh off the boats.

And also please make sure this smart-ass (if this is an intentional thingie) is not a Nepali citizen who has posed his way to the US as a Bhutanese refugee. I believe there are a few thousands of them here already, from the pre-resettlement era, and a few I have met from this group have been the ones dissing other Nepalis in less permanent status!
