In my reading and film this week, I learned about the criteria for citizenship. To be precise, I also heard that Americans are xenophobic. In comparison, the United States treats European immigrants and immigrants from other regions except European immigrants with obvious differences. If you are a European immigrant, because your skin color is white. You may be assimilated in the American mind, but if you are not from Europe or your skin color is not white, you will never become a citizen. No matter how long you live in the United States. In other words, it is far easier for European whites to become citizens than other skin colors, and other immigrants will be required to test their loyalty.
For me, citizenship is an identity. It includes the contribution that the country needs to the society, such as tax payment, medical care, education, etc., which can be used in priority to foreigners. Military judges and others are regarded as part of the United States. They belong to those who serve the United States and put American interests first.
