Thank you, ImABule and Sidsmt! How should I send the letter and updated form? By email?
You have AOR1 but no SA correct?
If this is the case, have your husband refill and sign the form. Scan it and upload it via case specific enquiry and send it to CPC-M.
This way you have an email record of trying to correct the issue as soon as possible.
Once the file is transferred to Manila, have him send the physical copy to MVO as well as another CSE to MVO through email.
In the cover letter use all the personal information about you and your husband as you have (file number, name, dob, UCI etc) and simply state that you have realized an error in form IMM5669 and you want to correct it.
