As the Trump administration "cracks down" on China's trade practices, especially those in industries where Beijing seeks to dominate, the US consular offices will enforce a new time limit on visas.

Rather than the typical practice of issuing visas for the maximum amount of time, the US consul will limit Chinese graduate students in fields like robotics, aviation, and high tech engineering to one year. Those in STEM-related fields will also face tighter visa policies.

The changes, set to begin June 11, will also shorten the validity of some visas already issued to Chinese citizens.

In an article in The Hill, a State Department official said, "Although the large majority of visas issued to Chinese nationals are issued for the maximum validity, consular officers may limit the validity of visas on a case-by-case basis, as appropriate to the circumstances of each case."

Additionally, Chinese students seeking visas will need to acquire "special clearance" from multiple US agencies to work as researcher or managers for companies that require high scrutiny. The clearances could take months for each application. 

Trump wants to crack down on China's trade practices, specifically those related to cutting-edge industries. 

In December announcement of his national security strategy, he said that the US would review and tighten visa policies to "reduce economic theft by non-traditional intelligence collectors."
