Do American minor children need their parents to accompany them when they approve immigration to the United States for the first time?

It doesn't have to be accompanied by parents, but also depends on the child's specific age and English level. The older a child is, the higher his English level will be, and it makes sense to be accompanied by an unaccompanied child or others. The United States attaches great importance to this matter, and they will ask about the relationship between the escort and the child. If the relationship is too far away, they will get suspicious. Escort has good English, preferably American citizen or green card.

Although it is not necessary, it is definitely the most suitable arrangement to be accompanied by either parent, which can greatly reduce the possible troubles when entering the country.
