American astronauts are going to Mars. How can I join them?

First of all, you should immigrate to the United States and become an American citizen (the specific methods can be: studying abroad, investing in immigration, skilled immigration, or giving birth to your own children in the United States, and the children can automatically acquire American citizenship, or fall in love with Americans and get married. When you become an American citizen, you can register directly with NASA. If they continue to select astronauts from the people to go to Mars, if not, they can join the US Air Force, but they must be pilots and ground crew. After becoming an astronaut, you should express your wishes to your superiors: you want to go to Mars, and after discussion and approval by your superiors, you can go to Mars ~!
