You have immigration consultants who are licensed, but your business would not have to be licensed. I say that because in the funeral business, which I keep bringing up, the funeral home has to have a licence and is accountable to the body, and the funeral directors have to be licensed and are accountable.
I worry about your business. I'm not questioning it whatsoever, but I'm worried that someone could actually think you were breaking the law because they might think you're giving immigration advice.
