N-400 一年多了都沒消息，查了TIME FRAME, 大約比正常過了6個月。請問：
1. 這DELAY 會是怎樣的原因？
-Case by case, had to say.
2. 如果我的CASE有問題，移民局會讓我無期限等待嗎？
-They will contact you if they need you top explain something.
3. 如果問題嚴重會不經INTERVIEW直接REJECT APPLICATION 嗎？
-It should be "deny your application", "not reject", if you have got the N-400 receipt. They will contact you first and inetrview you or ask for explanation or provide more information.
如果REJECT N-400 APPLICATION會影響我的綠卡嗎？
-Depends. If they find that you had fraud in the green card application, then your green card may be revoked. Otherwise, it should not affect the green card validity.
4. 我能做什麽嗎？-
-Contact USCIS for your case status/progress.
