回複：請問8老師, 如果辦理侄女過繼到我這裏

這樣她就可以在美國上公立高中，有多難？值得嚐試嗎？她目前在我家住了有一個多月， 插班上當地的八年級，她的旅遊簽證六月到期。
-The problem is that how she can maintain her legal status and adoption does not solve this problem in a short time. She may change her status to F-1 (F-1 can be one year in high school, but may need to pay tuition) or extend her B2 status.

By the way, adoption is complicate, and the procedure is very different based on your status (US citizen, green card holder or non-immigration status holder).
