I have a friend who is chinese but lived in south africa for many years. therefore she has both chinese and south africa passport (but on south african passport changed her last name to married last name). Later her daughter applied greencard for her to come live in the state (applied with the last name on south african passport and all documentation on south african passport).Now she wants to travel to china with chinese passport and back to USA , is it possible? (cause greencard applied with south african passport)
thank u .
