Can I apply for immigration of collateral relatives with a US green card?

Green card-permanent resident status in the United States. At present, only spouses and unmarried children (including over-age and underage) can be applied;

Others (parents, married children, brothers and sisters) can only submit applications if they are naturalized in the United States.

Other collateral relatives can only invite them to visit relatives and travel, and the cost of such a non-immigrant visa is about 1000 yuan.
