1. 孩子绿卡和驾照的地址都是我们在加州的地址,需要申请移民局更改吗?
-No. But he needs to file AR-11 (online or paper filing) now.
2. 孩子在大学每年的都要换宿舍,这样的话,地址每年都不一样,需要每年通知移民局吗?
-File AR-11 each time.
我担心文件寄丢。
-May use the Department Address or A professor's Office Address in the "Part 4. B. Care of" of N-400 (Talk to the professor about this issue and ask him/her to foward the letter to your child)
申请公民入籍是在是第一次,而且情况有特殊,也只好一次又一次的麻烦您了。
