8老师您好，我今天帮我妈妈提交I539延期表，其中有一个问题我发现我填错了。我妈妈是06/23/2019进入过美国，然后这次05/05/2022来的，问题问我妈妈last date arrive to US, 我填成了19年入境的，现在怎么办啊，这样case 会被deny么？
-Wait until you get the receipt notice that tells you USCIS received your I-539. The notice will have a receipt number, which will make it easier for USCIS to find the form you filed. Then you should call the national USCIS Contact Center at 1-800-375-5283, explain the mistake, and request that they fix it.
