Why banks send a form W-8BEN if the person is a Foreign citizen who is not a US resident, does not hold a US resident card or green card, lives outside US, works outside US and does not have a SSN, but have a US bank account as a convenience to pay property taxes he/she owns in the US?
For this previous purposes, funds are wire transferred to the US account and sometimes, but very rarely, deposited directly when visiting the US.
