Hello Sreenivas ,

If the signature is not visible in your JEE Main Session 1 application form , it's possible that there was an issue during the upload process .

Here's the following steps :

1. Log in to the NTA JEE Main portal : Go to the official JEE Main website and log into your application account .

2. Check the Application Status: Verify if there is any mention regarding  incomplete or incorrectly uploaded details , including the signature .

3. Correction Window : NTA usually offers a correction window before the exam where you can update or correct details like your signature , photograph . You can make changes during that period .
