Companies are always going to lay people off, because they can and it is in their financial interest to do so when the shareholders or investors demand cutbacks. AFAIK, Amazon even has a formalized stack ranking system where a certain percentage will be laid off every year to make room for new talent. This has nothing to do with visas or immigrants. If you want to stop that, you need better worker protections, but that's a separate discussion.
