Immigrated to the United States at the age of 60

Understand your difficulties. To tell the truth, it is already difficult to learn a new language at the age of 60, and you have to live in a new environment. Although your children may also want you to enjoy the good conditions abroad, they also ignore your lack of "adaptability".

Of course, not all can't be overcome. If you really want to emigrate, I really suggest you start learning English early. As long as oral practice is enough, don't look at spelling first. The point is: imitate more. Find a basic listening practice material online, preferably with Chinese-English translation. If he reads one, you should read it, and it's better to record it together. Watch 10 minutes, then go back and listen to it with your own ears. What's the difference between what you read and the material? Start with simple greetings and daily expressions.

Good luck!
