请问到美国读会计研究生半奖学金申请成功的概率有多大？？即使得到了半奖学金，剩余学费，生活费通过自己平时的打工能负担吗？？

It would be difficult to receive a scholarship if you study a business related major. You can work up to 20 hours per week on campus during the school session and 40 hours in summer time. You might be able to pay your rent if you do not mind to share an apartment with others. Tuition varies. It is tough to cover both tuition and living expenses same time. Some foreign students accept off-campus jobs without proper work permission. For those students, they are subject to deportation if they are caught by the U.S. immigration authority. there are a lot more that I could not cover everything here. good luck.
