Vancouver technologist Darren Barefoot was invited to Redmond by the MSN Search team but was stopped by Immigration and denied entry.

Ultimately, the customs agents concluded that because Microsoft was covering my flight and accommodation, I was being compensated for consulting activities. In order to enter the country, I'd need a work permit.

Sorry, Darren. We miss you already. We even asked the rain to take a few days off and invited the sun out to play just for you.
