In America, you first become a legal permanent resident (we would say you have a “green card”). Once you have lived here for five years then you can apply for citizenship. The whole process is slow and can be somewhat arbitrary.

Another option is to enlist in the US military. After serving for several years you can get preferred status for citizenship.

As others said, this is a difficult time to be an immigrant in America. The current government is arresting and deporting legal residents based on flimsy accusations. You should consider waiting for Trump to be gone, or look at other countries.
