Can a China person who marries a green card have a green card?

This intimate friend, who is married to a China native or a local citizen (naturalized citizen) and holds a foreign green card, can apply for spouse immigration reunion and green card. Legal immigrants can apply for a spouse green card, but the scheduling time and review are different. For example, if you marry a China person with a green card, it will take at least 3-5 years to apply for a green card. If there are any obstacles, you may not be able to apply. It takes a long time and it is difficult, and the relationship between the two sides may not be able to support this long-term separation.
