羽絨, it depends on where you are planning on getting it in hk. there are places that sell cheap 羽絨 in u.s. but if you want one that has higher qualitiy, then it might be more expensive. but if you want it to suit the weather better, then i would recommend you to get it in u.s. for school, don't bring any files or papers because the papers and files in u.s. are different. but if you want to bring pencil or something like that, thats okay too. you also need to bring your report cards of at least the last three years. Bring more clothes, though the ones in u.s. suit the weather better, the clothes in u.s. are more expensive, but the quality is good, so it depends on if you want it to be cheap or if you want it to be high quality. you might also want to bring some pills for cold and flu and etc because it is really expansive to see the doctor in u.s. without insurance or mediacid. i have no idea how you can get large amount of money into u.s. because my mom is the one who took care of those stuff, so sorry.
Hope I helped. =]
