OPT延期状态变成Alien Registration Number was changed是什么情况阿？

今天收到uscis发的email：。。。your Alien Registration Number was changed relating to your I765, APPLICATION FOR EMPLOYMENT AUTHORIZATION.
During this step, USCIS initiates the background checks of the applicant/petitioner and identifies issues that may need to be addressed either during an interview or by asking the applicant/petitioner to submit additional information or documentation. USCIS reviews the applicant's/petitioner's criminal history, determines if there are national security concerns that need to be addressed, and reviews the application/petition for fraud indicators.

有谁碰到过类似的情况吗？我现在的OPT已经到期了，是不是需要我提供更多材料阿，问学校也没说缺什么。

应该就是approve ， 马上要发EAD卡了

谢谢了！

请问什么是 Alien Registration Number ，我也申了OPT，没有这个number

今天变成card production了。我在网上查了好像ARN就是OPT卡上那个号码。。

恭喜楼主了
