尊敬的8老师，
感谢你的及时回复。补充说明如下：
I130 was approved on 1/13/2021.
My sister is in China.
I received "Notice of Immigrant Visa Case Creaction" from National Visa Center dated 3/24/2021. Following the instruction, I logged on CEAC. The case is still there but I can not process (The pay button is grey). The letter stated "If you do not log into CEAC for a period of one year, by law the department of State must terminate your visa application."
请老师指教如何处理。十分感激！
祁珉
