I am not a legal expert but this is from the application form of Citibank:<p><pre><code>  7) US PERSON CERTIFICATION:
     I&#x2F;We certify under penalties of perjury that (Please tick one box)
     (i) I am&#x2F;We are not a U.S. Person (as defined below)
     ...
     “U.S. Person” as used by the Bank means any of the following:
     ...
     (ii) a United States resident; meaning:
       ...
       d. an individual with a U.S. mailing address or U.S. telephone number.
</code></pre>
Make of that what you will.
