There's no harm in trying. I think it only costs $160. Just make sure that you give the consul/VO an impression that you will not overstay in the US, and you have a legitimate reason for visiting the US. My sister, who's a permanent resident here in Canada, did not have a hard time getting a US visa. I also did not have a hard time getting one, but I applied in the Philippines. We both brought a lot of papers, bank statements, etc but the consul did not even ask for anything.
