I opened both Euro and USD account at HSBC over a year ago. I have had no problems receiving wires from aff programs and then wiring the funds to my account here in the US. If you are a US affiliate and have an offshore account or are considering it as an option, please refer to the following thread:

There are some pretty stiff penalties for failing to report correctly on these foreign bank accounts.
