YC does issue invitation letters for founders traveling from outside US. We interviewed with YC and 2 of our co-founders flew in from India (they already had their B1 visas).

Just write to them and they should be able to send you the letters through HelloSign.

Good luck for your interview!

Thanks, aviv!

In addition to all the wonderful resources already suggested above, you should check out the MOOCs on Mathematical Thinking (https://class.coursera.org/maththink-2012-001/class/index) and Algorithms (https://class.coursera.org/algs4partI-2012-001/class/index) on Coursera.

Be sure to check out Loosecubes.com, which is a great source for finding free co-working spaces.

Great idea! Would also be fun to fly there together!?
