Hello aspirant,

If there is any mistake or problem in your uploaded photo or signature NTA will inform you through SMS to your uploaded number or through an e-mail to your ID. So, please kindly check them all, even spam folders too. If you got such texts from NTA then wuthin three days do the needful. Please read e-broucher and all rules of NTA correctly and fill up your form very carefully. Hope this will help you, and no need to panic about anything.

All the best!!

Satyam, NTA did mention that the Signature should be in black but the application will not be rejected just because of the colour of the ink. Unless the images uploaded do not follow the said guidelines like dimensions and format, the application will not be rejected. So do not worry about that. If NTA finds your signature to be incorrect, it will notify you.
