What are the sensitive majors in applying for a visa to study in the United States?

Applying for a visa is the last stage of studying in the United States, and it is also a very difficult stage. Whether the visa is passed or not determines whether you can study in the United States. An important aspect that affects the difficulty of visa application is your major in the United States. Some sensitive majors or those with immigration tendency are easily refused visas. If you apply for these majors, the preparation of visa materials and visa questions should be more detailed and comprehensive, which will increase the chances of visa passing. Today, Tiandao Bian Xiao will take stock of those sensitive majors studying in the United States that are not easy to sign.

Information security professional information security

Technologies related to encryption and decryption systems to ensure the security of secure communications, videos, data and related software. Data security is very important for a country, so the United States is not very willing to educate its own technology to students in other countries, so as to avoid its advanced technology being used by other countries!

Long-distance shooting and investigation specialty

Remote sensing technology is an unpopular major and belongs to the high-tech category! Although the remote sensing technology we know is more or less civilian, it can also be applied to some reconnaissance projects-such as the reconnaissance capability of drones and remote-controlled aircraft, and so on! Even related to the satellite remote sensing technology industry! This major will also involve knowledge of other disciplines such as optics!

Advanced computer/microelectronics technology major

Promoting the development and deployment of computers and software in missiles and missile systems is conducive to the development and production of nuclear weapons. Among them, the technology includes: airborne early warning and positioning, electronic countermeasure processor, microcomputer compensated crystal oscillator and so on.

Material science and technology specialty

The material we are talking about is not the material science and technology major of clothing or civil equipment! New composite materials involving airplanes, spaceships and submarines! The selected special materials have special properties, which can develop electromagnetic attraction, magnetism and superconductivity.

Force. These technologies involve advanced metals and alloys, non-composite ceramic materials, ceramics, cermets, organic carbon materials, polymer materials and so on. Therefore, visa officers will regard such high-tech majors as key protected majors.

Therefore, you will be repeatedly questioned during the interview!

Chemistry and bioengineering is one of the favorite majors of domestic science students! You can engage in high-tech research and pharmaceutical industry after graduation! This highly respected major is also considered as a sensitive major because it can use professional knowledge to manufacture dangerous goods.

Navigation, Guidance and Control Specialty

These capabilities directly determine the launch accuracy and lethality of the two unguided and guided weapons. Technologies include technologies related to internal navigation systems, tracking and terminal identification equipment. Flight and aircraft control system.

Missile specialty

Technologies related to aircraft and missile systems will be classified as protection majors in the United States, so even if they apply, they will be banned. Satellite launch vehicle development technology, including ballistic missiles, space launch vehicles, space rockets, unmanned aerial equipment and payload aircraft.

Propulsion system and on-board system of aircraft and missiles.

Propulsion technology related to near-earth hypersonic flight of aircraft and missiles. Many of these technologies are dual-purpose, including liquid and solid rocket propulsion system technology, independent rocket state or separation mechanism, and aerospace.

High-tech technologies such as test equipment and technology for heat-resistant and high-performance structures and propulsion systems are the secrets protected by the highest state. Even in China, ordinary people are not so easy to reach, let alone foreigners! Similarly, we can also

Understand why American visa officers will consider your visa application!

These majors are sensitive majors that are very difficult to apply for a US visa. If you decide to study these majors in the United States, you must prepare your visa more carefully.
