A notice of intent to deny or NOID is a formal statement from USCIS that it has determined that the applicant is ineligible for the immigrant benefit requested. However, the USCIS will grant the applicant an opportunity to overcome this determination and demonstrate that he or she is eligible.
Absolutely not. A well crafted response that addresses each specific point made by the USCIS will result in the application being approved.
The USCIS will grant a maximum of 30 days to respond.
Typically the decision will come quickly after the response is filed but it will depend on the complexity of the NOID and the normal processing time line for the type of filing. It can be as little as one week but is normally concluded in less than two-three months.
