Hi, I just got accepted to the GPS Division with Environmental Science&Engineering option in Caltech. My POI said there would be an Open House on Feb 18&19, but I did not get official guide of the Open House, for things such as the reimbursement of airfare, the lodging and the schedule. Do you have any news? Also I saw you had an interview of Stanford. I am also applying for Stanford ( Earth System Science) and was invited to the Department Visit (on Feb 16) to have a more detailed and in-person interview with POI. Are you also required to have an in-person interview?
