在幫高齡母親在線填寫入籍申請N-400, 想請教大家以下問題該如何填寫？
1. 有一項要求提供婚姻狀況證書， 父親已經去世多年，母親一個人，我在母親的婚姻狀況選的是widowed，那這一項還需要上傳任何婚姻情況的證書嗎？
-Yes. Provide her marriage certificate and your father's death certificate.
2. 最後還有一個問題，弟弟是作為母親的綠卡成年子女， 幾年前移民美國， 他還有一個孩子由前妻監護，孩子隨弟弟一起申請綠卡申請，當時在national visa center online applicaiton 表格裏是選的follow to join. 那麽如果我母親變成美國公民，那弟弟的孩子的follow to join 是不是就失效了？
-If your brother's green card was obtained under your mother's sponsor (i.e., your mother filed I-130 for your brother) then, what you worried about is true. So, your mother had better not apply for the naturalization until your brother's kid immigrates into US. Otherwise, the kid's willl lose the follow to join benefits.
But if your brother's green card was sponsored by you (you filed I-130 for him), then his kid's follow to join will not be affected whether your mother becomes a US citizen or not.
還是follow to join 繼續有效, 因為主申請人我弟弟已經移民了？
先謝謝大家的幫助了！
