Nonresident Alien with ssn W8 or W9

I am helping a friend with some tax questions.

 

She is a nonresident alien currently live outside of the US.

She has SSN.

She has a bank account in the US.

 

The bank asks her to file a W8 form first, then when they know she has SSN, they ask her for fill out W9. 

W9 says a US person needs to fill out W9 but it doesn't seem like she fits into the definition of a US person.

 

If you are a U.S. person and a requester gives you a form

other than Form W-9 to request your TIN, you must use the

requester’s form if it is substantially similar to this Form W-9.

Definition of a U.S. person. For federal tax purposes, you are

considered a U.S. person if you are:

  • An individual who is a U.S. citizen or U.S. resident alien;
  • A partnership, corporation, company, or association created or

organized in the United States or under the laws of the United States;

  • An estate (other than a foreign estate); or
  • A domestic trust (as defined in Regulations section 301.7701-7).

She is not a US citizen, an estate, or a domestic trust. Does have a bank account in the US make her fall into the category of partnership?
