我第一次申请F2A绿卡的时候，因为排期未到（我看错了priority date，以为排期到了）申请被退了回来。我看到uscis给的notice上写着让联系National Visa Center, 我也不懂就发了邮件给ASKNVC，结果就被建立了Case。后来我发现跟我本意不符后，我就发邮件要求给我消掉这个案子，因为我还是要通过USCIS来申请绿卡的。我联系NVC就是问一下，没有给他们寄任何材，没想到搞出这么多麻烦。收到的最后一封来自NVC的邮件如下：
The National Visa Center (NVC) received your inquiry regarding the immigrant visa petition: GUZxxx filed by xxx on behalf of xxx.
Thank you for telling us that xxx plans to adjust to lawful permanent resident status in the United States. If xxx has not already done so, he or she should contact U.S. Citizenship and Immigration Services (USCIS) for instructions. xxx should disregard any instructions we sent to him or her, since those were for immigrant visa processing. You can contact USCIS at 1-800-375-5283 or by visiting their website, uscis.gov.
We will tell you when USCIS asks us to send them your petition.
Do not let more than one year pass without contacting the National Visa Center (NVC) concerning this visa petition. If a period of one year passes from the last date of contact (by telephone, mail, or email) with the NVC, the case will begin the termination process. Even if xxx plans to adjust status with USCIS, this case should remain active in case his or her circumstances change in the future.
2.i-485表上有个问题是问：Have you ever applied for an immigrant visa to obtain permanent resident status at a u.s. embassy or us consulate abroad? 我应该回答yes还是NO？
3. 我现在才发现我已经超过 一年没联系NVC了，What should I do？
