International adoption creates a greater gap between the parents and the child's culture. Not only does race factor into adoption but international adoption also create barriers between the child's biological culture and the culture that they are being brought into. Depending on the age of the child, ethnocentrism becomes stronger as the age of the child increases. Culture shock is a factor associated with opposition to international adoption. Specifically, as more countries try to promote domestic adoption and keep adoptees in their countries longer, those children are getting internationally adopted later. This contributes to the cultural gaps as the wait times increases and children have begun making relationships with the people, environment, and culture around them.
