However, the US's China policy is not friendly. Whether it is the "Announcement No. 10043" signed by Trump or Biden's "high wall" barrier, the essence is to prevent the flow of strategically advantageous technologies to our country.

Therefore, starting from the Trump era, the United States has imposed various restrictions on Chinese science and engineering students and scholars going to the United States on the grounds of so-called "national security". From June to September 2020, the US State Department cancelled more than 1,000 Chinese graduate students and scholars studying abroad. As for the visas of scientific researchers, until July this year, more than 500 science and engineering students were still denied visas to the United States. Now, in order to maintain the financial revenue and overall interests of their higher education, the United States has to loosen some restrictions.

Therefore, in April this year, the US State Department stated that from August 1, Chinese students can fly directly to the United States without being quarantined in a third country for 14 days. On this day, the US embassy in China fully resumed the business of student visas.
