HEY! Congrats!
Just wanted to share what little information I know about Indonesia and Fulbright. My favorite professor was granted a full grant to do research on agriculture in Indonesia, BUT her visa from the government never went through. She kept getting denied. I think it got to 6 months after she was supposed to have left. At that point she withdrew. Apparently, even if you are waiting for a visa for 2 years and never actually leave the US, that will count as your time as a fulbright grantee. So she withdrew to reapply later. Anyway, I think that was the story. The important part for you, I guess, is that she received the grant, was ready to go, but it fell through. Hopefully that won't happen to you!!! But I'm assuming that's why they included all that in what they sent you.
