刚拿到的case number(大概1星期前noticed),但是去这个网站上查
https://egov.uscis.gov/cris/caseStatusSearch.do
得到这样的回复:
Your case can not be found at this time in Case Status Online. Please check your receipt number and try again. If you need further assistance please call the National Customer Service Center at 1.800.375.5283.
请问是怎么回事?是不是最近移民局网站出了问题还是我的case有问题?
谢谢!
