According to the official website https://viteee.vit.ac.in/ , the online registrations for VITEEE have been extended until July 15th. So the possibilities of opening a correction window might happen only after July 15th. Last year, the correction window was made available but Candidates could not edit all the fields. And you haven't mentioned the correction that your application might need. So please reach out to the helpdesk at: ugadmission@vit.ac.in  to check the possibility of making corrections to the application form.
