Quick Employer Forms does not support foreign addresses. As a workaround, enter your business address in QEF and mail the 1099-MISC to the Payee in a manually addressed envelope. The IRS doesn't much care about the address on the 1099-MISC - they just want the SSN to be correct.
The recipient will file his or her tax return and provide the only address the IRS needs - the one on the return.
