同时给爸妈在网上申请公民填N 400, 结果上周四提交后今天才发现我爸的A number被我给写错了。 (尾号778写成788) 通过account 里的inbox 给留言了， 打算明天给移民局打电话。请问他们电话现在好打通么？我需要重新填申请么还是可以直接给改 A number么？
-Have you got the receipt number for his N-400 filing? If yes, you should call the national USCIS Contact Center, explain the mistake, and request that they fix it. USCIS contact number: 1-800-375-5283
If you don't have the receipt number yet, wait until you get the notice that tells you USCIS received it. The notice will have a receipt number or other case identifier that will make it easier for USCIS to find the form you filed.
