“US schools will largely resume in-person classes this autumn, so student visa appointments can be made as normal, but the other visa applications to the US have not yet been reopened,” an employee at the Beijing-based consultancy New Oriental said.

“It is just that some graduate students may be in more sensitive areas of study, so there may be a certain impact on the visa approval process but this will not affect undergraduate visas.”

The resumption of visas comes ahead of the autumn semester for US colleges in September, and the strong number of applicants are a sign that Chinese students are still eager to head to the US after a dip in interest last year.

In May, Beijing hit out at the US after a Chinese student was denied a visa because the US had suspended issuing visas for senior Chinese officials employed by four intelligence and law enforcement departments and their immediate family.

At the time, the US embassy in Beijing said it was a temporary suspension applied to some applicants because China was not adequately cooperating in accepting the return of its nationals under final orders of removal from the US.

China is the largest source of international students in the US, with more than 380,000 active students in the country last year, but this was nearly 92,000 fewer than the year before, according to official US data. Along with students from India, the second biggest group, the two countries still made up 47 per cent of all international students in the US last year.

The US last year barred foreigners who had been to mainland China within 14 days from entering the US. But in April, US officials said students with valid visas could enter the country 30 days before college started.

Non virus-related tension between the US and China has been an additional factor. Last May, the US suspended the entry of Chinese nationals who receive funding from, or work for, any Chinese entity supporting Beijing’s “military-civil fusion strategy”.

Qiao Xiangdong, owner of the Beijing-based Gewai Education agency, said most of the students he worked with received US visas except for one who had studied at the Beijing Institute of Technology. The institute is one of the seven universities with links to China’s military and defence industries that are directly supervised by China’s Ministry of Industry and Information Technology.

“The visa approval period has not changed but there are stronger checks on postgraduate students,” he said. “It is more rare for undergraduate students to be denied visas or to be scrutinised.”

Qiao said Chinese parents were concerned about sending their children to the US because of issues such as Covid-19, gun violence and racial discrimination, but that the level of overall interest from Chinese students had not dropped, particularly for high-performing students.

“There are many benefits for Chinese students in the US that other countries cannot compete with, including the great job opportunities,” he said.

“Of course, a small minority of people are concerned about the visa situation, particularly for those in STEM (science, technology, engineering and mathematics) and military-related fields, so they may opt for other countries with more relaxed visa policies like Britain, Switzerland or Canada.”

Another Beijing-based Chinese education consultant, surnamed Wu, said that while the US might carry out background checks for postgraduate students in STEM fields, the students “in most cases can get the visa if they are paying tuition themselves or have received US scholarships”.
