The address displayed on your profile should reflect your physical location. Please keep in mind that your account may be flagged for location inconsistencies. If you're moving to a different country, you'll need to update your address as it should be your real, permanent address. This is for tax purposes. When you make the change, you must be logged in to Upwork from the country you are changing to. There is no process other than going to your Settings > Contact Info and updating your address in the location section.
