The first discussion got flagged, probably because the source article was badly sourced and had too little detail. It didn't mention visas for example.

The claims are unsubstantiated. From the source article:

> Disclaimer: The identity of the news submitter has been verified by us. However, we have not received any confirmation or verification from Walmart regarding the information provided.

Without proof or corroborating evidence, this is social media rage bait making the rounds. Proof and evidence are of course welcome to substantiate the claims being made.
