Hello guys. Ok here is my situation. I applied for USC (N-400) May 4th. On May 30th I got an e-mail saying that USCIS sent me my BIO appointment letter. It has been two weeks and I have not gotten that letter. I truly believe it got lost in the mail. I called the customer service number and both times they said that I have to wait 30 days. I asked her to confirm if the letter was indeed mailed out on the 30th and she said it that it was. I asked if it was possible to get another letter or if it was possible for them to fax me a copy of it so that I did not miss my appointment and she kept saying I have to wait 30 days. I then asked her, what happens if I miss my appointment that's on that missing letter that you guys sent, and she refused to answer. She just kept saying to wait 30 days. Worst service ever! My question is, what happens if I miss my appointment, which I am sure that I will now. What will USCIS tell me when I call them June 30th and say that I missed my appointment because I never got the letter? Any help would be great guys. Im starting to freak out.
