What happened to Zhao Panshu, who resigned as a teacher in order to obtain American citizenship and join the US military?

Compared with China, the founding history of the United States is a drop in the bucket, but the strength of a country is not measured only by the length of its history. As a world power, the United States is now developing its own economic construction by selling guns and ammunition to all parts of the world. At one time, the United States was the world hegemon, so many people in China wanted to immigrate to the United States and get a better life, including a man named Zhao Panshu who resigned in order to join the United States.

Zhao Panshu, like many foreign students from China, went abroad for further study and to improve his strength and competitiveness. However, some foreign students will return to China to build their motherland after their academic achievements. However, it is understandable that Zhao Panshu chose to stay in the United States for a better life after going abroad. After all, everyone makes their own decisions in life. After finishing his master's degree in the United States, he also worked as a teacher in a university in Texas. This life lasted for a long time.

But because he is not an American citizen, his promotion and future development in the United States have great limitations. By chance, he learned that he could become an American citizen as long as he joined the American army, so he joined the American army, where he was treated unfairly because he was from China with yellow skin, but the more he did, the more he wanted to obtain American citizenship.

However, after Trump took office, this policy changed a lot, and Zhao Panshu lost the opportunity to obtain American citizenship. But this is not the worst. To make matters worse, Zhao Panshu gave up his China citizenship before joining the US Army, so he is now a stateless person. Now he can't do any decent and high-paying jobs in the United States, so he can only do odd jobs to make a living. What do you think of this?
