The green card problem in the United States, according to the pro-visa, bring your wife into the country.

This is an important decision. Please discuss it with your parents. Because it means whether you choose a green card or a girlfriend. If it's according to your idea, I suggest you give up the American green card. If you are not an American citizen, you can't immigrate to your wife quickly. Citizens can get a fiancee visa for their fiancee in six months, and a green card for their wife in 1 year. But if you want to become a citizen, you must hold a green card and live in the United States for five years before you can apply. You can't live in China for long. If you are not a citizen (green card), your girlfriend must marry you first, and then apply for a reciprocal date, usually 5- 10 years. Husband and wife have been separated for too long to wait. Since you think you want to develop in China, give up the American green card. Besides, your information has just arrived in Guangzhou, and you have to wait for a long interview notice.

Working in China, only going to the United States occasionally. If I visit my parents and relatives, I can apply for a B 1/B2 visa. Generally, you can get a 1 year multiple valid visa now. And if you renew your contract in the same place, you don't have to go for an interview, which is very convenient.
