I'm almost 22 years old now. /kloc-immigrated to the United States at the age of 0/7, and didn't learn any English at that time. After I came, I applied for esl, but nothing happened.

It's a pity to give up the green card. You are only 22 years old. What can't you learn? Don't lock yourself up. People always have to adapt to the environment. To go out and integrate into this society, to live is to overcome your cowardice and timidity, communicate with others more, and find a friend who is willing to communicate with you first, and you will learn quickly.
