It is a bit easier to be admitted as a Master student than as a PhD student in the States. Usually Master students have a few opportunities to receive financial aids from the universities and the departments, and universities prefer those students to enlarge their income. But in the States, PhD students are regarded as preliminary researchers and they are usually paid by the departments and their supervisors. In this case, the recruitment of PhD students is more strictly.Some universities of good reputations even provide many opportunities for students to pursue their master degrees, i.e. Stanford, Columbia and U of Southern California. But PhD applications there are extremely competitive.However, if you want full financial aids you have to apply PhD rather than Master. It is possible for a Master student to be awarded full financial aids, and the opportunities are rare.Sorry I cannot type Chinese now. There is no concept like "kao bo" or "kao yanjiusheng" in the States. I have never heard that in the States people like "kao yanjiusheng". In fact if they could get very good job offers, most of them will choose to work. Besides, degrees are also important in North America. For example, for some positions, especially in some academic and instrial research, PhD degree is a must.I can explain in Chinese later if you need further information. Hope it helps.
