I really thought about the technology ban, and I thought about the past. The development of China's space industry is really not easy. I have to say that the researchers are really working hard. China's Beidou satellite system, the No.5 lunar exploration plant, the Mars exploration project and today's space station construction have all achieved complete success. It is certainly not easy for any country to realize so many projects in a short time.
Generally speaking, China Space Station has "opened the door" for the world, as long as it develops everything. Of course, not all countries can definitely enter, and China also needs to review the space station project. The United States, Canada, Britain, Australia and other countries became extinct because the project did not meet our national standards. Although we are open, we also have our own standards, which are not adopted at random. You can rest assured.
China Space Station may become the only space station in the world in the future. According to the previous plan, the International Space Station may be "retired", so the China Space Station may become the only space station in the world. In the future, many countries in the world will "rely" on the development of China's space station, unless they build their own space station, or do not conduct outer space research, and do not want to develop. This possibility should be extremely low. Now any country in the world wants to develop, and it can only rely on its ability to build a space station independently. And you know, now only China has the strength to build a space station in the world. Although other countries say they have plans, whether they have the strength to build them is an exception.
Former US President Trump announced at the White House that he supported the adoption of a draft bill called "RAISE", the core of which is to reduce the number of legal immigrants, limit the number of relatives immigrants who currently account for the largest proportion, and limit the number of low-skilled immigrants. Reduce the number of green cards for refugees, improve the quality of immigrants, and cancel the green card lottery system. From the trend, the proportion of high-tech immigrants will increase. In other words, it is relatively easier for students who choose high-tech majors to get green cards than students who choose other majors. Aerospace engineering is a sensitive major, and its salary is much higher than other majors. However, the employment of international students will be restricted to some extent, and they will still be inspected regularly after being hired by American government departments. Employment: Graduates mainly work in the U.S. government and defense departments.
