DOS Case ID K1 Visa

[pepper297 63]

Hello!  We are trying to file online for naturalization for my husband.  To confirm identity on the USCIS site, they ask for the alien number (which we have) and the DOS Case ID.  I cannot find any paper that mentions that.  He came here years ago on a K1 visa, which is a non-immigrant visa.  Anytime I look up online where to find the number, they are talking about immigrant visas.  Does anyone have experience with this?  I wanted to file online but it is seeming like I will just have to file via the mail if I can't find it. Thank you in advance!

My wife's NIV in her passport (K3) from 11 years ago has a "control number" in the same place the case ID number is shown on the immigrant visas.  You might want to look on the original K1 visa and try that number.

@Nitas_man I tried it the other day just in case it would work and it doesn't.  I've looked through all the letters I've saved over the years from USCIS, his passport, his visa, all entry papers... but I do not see the case number.

Hi.

I just filed mine yesterday without doing that part and It seems it went through fine. I'm not sure that's for the N400.
