A Notice of Intent to Deny (NOID) is USCIS’ way of letting you know that they don’t expect your application to be approved. However, there’s no need to panic yet: the NOID will outline these reasons for denial and will give you 30 days to address the issues in a response.
USCIS issues NOIDs when the officer reviewing the application determines that the applicant has not met the eligibility requirements for the immigration status requested in the visa petition.
NOIDs should not be confused with a Request for Evidence (RFE). RFEs are issued when an application is missing pieces of evidence and the officer is not sure if they should approve or deny the petition yet. NOIDs are issued when sufficient evidence has been provided, but for other reasons the petition is still expected to be denied. Issues with eligibility can include new information about criminal history, or immigration status violations from the past.
