As we kick off this challenge, we want to provide a quick point of clarification about eligibility. The challenge is open to international participants, however to be eligible to receive a prize the Team Lead must be age 18 or older and a US citizen or permanent resident of the US or its territories. The Team Lead is the sole person who will accept the cash prizes on behalf of the team. Teams are encouraged to include participants from around the globe, and this forum can be a great way to find teammates.
You can check out the official rules on challenge.gov for further information on eligibility.
