If you keep your existing profile the nationality you have put on that profile will stay the same. The only difference is that there will be 'accessing from......' with the country you are currently in showing at the bottom of the profile. There's no way around that.
You CAN keep your profile and travel with it anywhere in the world, anywhere. I can't fathom where on earth you would be going where you want no association with the country you'll be residing in, which is making your situation difficult to understand.
