Oath ceremony

[pilee]

Need help please please. I missed my ceremony because I didn’t receive the note from uscis. When I got the note it was too later. The date of oath ceremony was the day before that I got the note. When I go online and check my case status it didn’t change anything. Can someone help me out what do I need to do please.

Looks like you posted three times.

That's frustrating for you. But no worries.. no big deal. Especially since it wasn't even your fault.
Just write them a letter and explain that the notification came too late (send it certified delivery if you want a paper trail).
They will simply schedule you for the NEXT available oath ceremony. Hopefully they will fast-track you to avoid any delays.
Stay calm... absolutely no big deal. :-)
