This is not immigration per se, but how often do you actually see issue with contract requalification?
For context: hiring remotely you don't want to set up a corporate presence in every country, that would be mind-boggingly complex & expensive — so instead you hire people as contractors or use an employer of record (EOR) like Deel to hire people and then you contract Deel.
The one risk with hiring contractors that will basically only work for you (though for sure, the contract should not make this a condition) is that in some jurisdiction is allegedly pretty easy to take these contracts to court and requalify them as employment contracts, putting you on the hook for back taxes and possibly fines.
I'm just wondering how much that stuff happens in practice, and how much of an issue it is when it happens.
