Q: I'm not a US resident and/or not a US citizen. May I apply for an E*TRADE Bank account?
A: Yes! You may open a non-transactional account, such as a CD. All you
need to do is fill out a W-8 form and send it in with your application. To
have a W-8 form mailed to you, send us an email message at
bankinginfo@etradebank.com and be sure to include your postal address.
You can also download this form from the IRS web site.

Very truly yours, Thomas
