Hi Jessica,
I applying with Americamp this summer 2014, i did back in June 2012 with Camp Leaders, which was a debacle, with Camp Leaders and Camp i was placed at, which is a another story, I slightly native doing the whole thing, back in late 2011, i was really rope into it at my University job fair, I am applying again, second time around because, I know how the whole system works, with the Camps, hiring you, the "Agencies" involvement, the sponsor" J1-Visa etc.. Americamp is far better then the other "Agency" as I am able to cover my own flights, which is reason i do through them. and salary/stipend is worth my time to do it. this time around. also they more upfront, one of the staff at Americamp where surprised of my vast knowledge of the program.
My advice to you to and anyone reading this don't apply unless you genuinely have the funds to support yourself during-after camp, back in June 2012 I was in world of trouble.,and learnt this the hard way.
