How can i register my son for space camp?

Hello everyone! I work in Alabama, USA. However, my family is back there in India. Last weekend i went to a trip at the Huntsville Space Museum in Alabama along with colleagues. It's an amazing place to be. It's designed to showcase the hardware of the U.S. space program and the facilities of the United States Space Camp. Moreover they organize a space camp for teenagers from all over the world, where the kids can get a hand-on astronaut training experience. Since my 14-year-old son has a keen interest in space i was wondering if i could enroll him for the camp, this summer. However, i don't know the details of the registration process for indian kids. Can anyone help me on this?
