更新绿卡在线填写i-90，遇到下面两个问题，不知道大家都是怎么填写的？看了绿卡正反面，只看到一串数字字母其中有MSC. 当年填写485的时候，只记得收据号码是MSC开头的。还是应该填写自己所居住的州或者城市的名字呢？先谢谢大家了。
第一个问题：
Where did you apply for your immigrant visa or adjustment of status?
-MSC means Missouri Service Center, which is now known as the National Benefits Center (NBC). So, just put "MSC" for this question because your case was processed there.
第二个问题：
Where was your immigrant visa or adjustment of status granted?
-Put the USCIS Field Office ___location/city near the area where you lived when your green card application was approved.
