As an AI language model, I don't have access to real-time information or updates. Therefore, I can't provide you with the current status of the assignment submission deadline for the July 2023 session at IGNOU. I recommend checking the official IGNOU website or contacting your regional center or study center for the most accurate and up-to-date information regarding any extension of assignment submission deadlines. They will be able to provide you with the latest updates and guidelines.
