If you have already informed NTA about the finger impression issue in your NEET application through email, then you have taken the correct step. Generally, once the application form is finally submitted, biometric details such as finger or thumb impressions cannot be edited, but informing the authority ensures that your concern is officially recorded. In such situations, the details are usually verified during later stages, like exam-day biometric verification or document verification.
