You shouldn't do anything. You can't cancel a SSN. If your not in U.S. you won't be taxed by the U.S.

By the road what is an "expat"?
You don't stipulation to do anything. as long as there is no money going into the account, it will just sit in attendance. If no claim is ever made, such as you retiring here, the money will just be a part of the total money in the SSI fund. Basically, duplicate as if you died.
Nothing, they won't charge you if your not making any money in the US.
For Tax Purposes .. only U.S. citizens are taxed world wide.If You are not a U.S. citizen.. don't verbs.
You and your social security number will spend eternity together. They wouldn't cancel it even if you died. But, I'm not sure what difference it will really make, if you stop putting money into it and never run any out. It's not like they're going to return your money just because you're leaving.
