What are the benefits of getting a PhD in statistics?
A doctoral degree is a credential signifying largely that you are capable of doing independent research at the highest possible level. It is not, in an of itself, a ticket to working in a particular industry or in a particular location any more than a bachelor's or a master's degree. In fact, PhD holders may have substantially more challenges in those aspects, because the additional qualifications make them unattractive for many positions in conventional businesses and industries. (You are unlikely to find a PhD working in a sales division of a multinational conglomerate, for instance.) 

The reason to get a PhD is because you are interested in problem solving and doing original work. If this doesn't describe your motivation, I would recommend against pursuing a graduate degree, because it will be a very long few years of your life which are not guaranteed to achieve the objectives you've laid out.
