In Andhra Pradesh, the process for uploading caste and income certificates after the initial application for programs like B.Sc. Nursing or any other course might vary depending on the specific university or college you applied to.

This is the most reliable way to get accurate information. Call the admissions office of the university or college you applied to and explain your situation. They can guide you on the specific procedure for submitting caste and income certificates after the application deadline.

Some universities or colleges might issue a supplementary document upload notice after the application deadline. This notice would specify the window for submitting missing documents like caste and income certificates. Keep an eye on the university/college website or your registered email for such notifications.

A few universities or colleges might have an online portal where you can upload missing documents after logging in with your application credentials. Explore the applicant portal of the university/college to see if such an option exists.

I hope it helps!
