In this case, it is difficult to obtain a long-term visa if the overseas Korean husband does not adopt his wife's children. In order to obtain a visa for the minor children of a remarried wife, the husband must first go through the process of adoption.

A similar case is the case with an immigrated youth whose mother remarries a Korean man and enters Korea, but is a Korean multicultural family, so the child can get a long-term visa even if the husband does not adopt his wife's children. This is because there are separate regulations in this regard.
