Why do American professors refuse China students to study PhD?

Because before that, his school had encountered six similar cases. The reason why these doctoral students leave is to find a job and get a green card. Before that, they entered school with the promise of studying for a master's degree and a doctor's degree, and their integrity was gone. For the school, all the efforts are in vain-each doctoral student is paid about $50,000 a year for tuition, health insurance, miscellaneous fees, experiment fees and computer fees, and paid monthly. The ultimate return of students is to take the rare opportunity of studying as a springboard for employment immigration.

In recent years, there have been many cases of China students losing their integrity overseas. For example, some international students take the doctoral degree of a relatively average university as a springboard, get a full scholarship first, and then apply for doctoral study opportunities in top universities the next year. Once the application is approved, they will suspend their previous studies and terminate their contracts with their former tutors. Some international students take advantage of the opportunity to study abroad for a doctorate to apply for a full prize. After completing the course, they stopped studying, did not do doctoral research, and left with a master's degree to achieve the goal of studying for a master's degree for free. In order to defraud many mobile phones, some international students signed lease line contracts with many mobile phone companies, chose the most expensive monthly rental price, and immediately canceled their bank accounts and packed them back to China after getting the latest models of mobile phones for free. The telephone company not only didn't get a penny of monthly fee, but also lost a mobile phone worth 500 to 600 euros. Therefore, some Spanish telephone companies began to modify the terms of contracts for China students, requiring that a deposit must be paid before the contract expires.

The misdeeds of the above-mentioned foreign students have had such a bad influence abroad that some American professors have made it clear that China applicants, including those excellent students from Tsinghua University, will never be considered in any doctoral enrollment plan.

Another source said, "Brain drain is still the weakness of China's economy". Citing authoritative data, The New York Times revealed that 62% of foreign students who obtained doctorates in science or engineering in the United States in 2002 stayed in the United States in 2007. Among them, there are more than 2,000 students in China, accounting for 92% of China's doctoral students in the United States, ranking first.
