I am a resident in a foreign country and only come to the US for about 15 days a year. I have a US bank account which is paying a small interest. When I opened the account I provided an address of a friend if mine in the US.
I have now been asked to submit a W-8BEN form.

Instructions for completing the form in the Non-Resident Alien Checklist state: "Complete one of the sections below that applies to you. Do not complete all sections".
However, both Sections 2 and 3 are applicable to me as far as I understand.

1. Is my understanding correct?
2. What should I do?
