Hey there pinge. Welcome to Fluther. What you need to do is this: Give us more details, make us feel like we’re actually helping a real tangible person. Tell us where you want to go in the USA (state, city, university/school), how old you are, why you want to go, where you’re from (Hong Kong? Shanghai? Beijing?) and any other details which would make this a really good question. By just simply asking us this one question and then putting “NA” in the details box (oh gosh what a horrible thing to see, somebody who thinks that it isn’t worth it to add details!) it makes us feel as if you can’t really be bothered to put enough time in giving us a quality question which can be answered with quality answers. Give us reason to answer you. We like answering people, not robotic questions. =)
