It happened to me too. If you are interested in a more detailed description, you could take a look at my postHi again @Sm1smom, My wife and I just received our NOAs (Thank you so much for your guidance on this so far. The AOS spreadsheet literally contains EVERYTHING anyone would need). However, my last name on the NOA contains an extra letter but the last name written after the 'C/O" section on the same NOA is correct which seemed odd to me. The name also includes the initial of the first 'middle name' only (but I'm assuming this part shouldn't be a great issue, please correct me if I'm wrong though)
Example:
Correct name:
John Michael Jack Doe
NOA:
John M. Deoe
C/O John Doe
123 S 123th Street, etc
We triple-checked the copy we have of the AOS package we sent and the name was NOT misspelled by us on any of the forms. We even made sure to include my name in all possible combinations in the 'additional names' section of form I-485.
(by combinations I mean (using the example above):
1. First name: John Michael Jack Last name: Doe
2. First name: John Middle name: Michael Jack Last name: Doe
3. First name: John Last name: Doe
and so on)
A couple of questions if you don't mind:
1. Have you seen this happen before? is it common?
2. Do we:
a. Call USCIS to correct the error (the NOA says to contact them to 'update' the information if needed)
b. Just submit an e-Request to correct a typographic error through their website (found after googling for a bit)
c. Not worry about this for now and correct it during biometrics/interview (and if so would this delay the process due to a new background check for the correct name?)
3. Do you know if this would affect the case processing time? Especially since we've only got 3 more months in the FY.
Thanks again
Basically, only the interviewing officer can correct it for you even if you submit an e-Request. I don't think the typo affected my I-485 processing time at all, however my bio notice had the correct name though. So just follow what @Sm1smom suggested - keep an eye on your bio & interview notice and communicate with your IO.
