For example, NY state had VERY different laws and obligations when it comes to a money transfer service. If you transfer money and you aren’t registered in NY state then you obviously don’t need to obey the regulations. For example all board member of the money transfer company need to submit financial documents.
However if an employee moves to NY, then the entire company would fall under the blanket of that because the company would need to register itself in NY. This is just 1 example. Colorado has laws regarding giving pay ranges on job postings. Many jobs no longer advertise in Colorado now because of it because they don’t want to fall under that blanket.
