I want to be present at the Apple event, What procedures I need to follow for that?

It appears the information that lobsterghost1 posted should have the answers. However, if that is not enough, and because Apple will not see your question here, it may be useful to contact an Apple regional office. I believe the closest one to your is in India:

This is a user to user only forum. Most of us have never been invited or attended a new product event in person. Most of us wouldn't even qualify.

Apple Event Invitation Process

To be invited to an Apple new product event, you typically need to be a member of the media or an Apple developer. Here are the steps for each category:

• Media Members: Apple usually invites select media members to attend their events in person. If you are a journalist or work for a media outlet that covers technology news, you should be contacted directly by Apple if you are chosen to attend.
• Apple Developers: If you are an Apple developer, you can attend the annual Worldwide Developers Conference (WWDC) in person. To do this, you need to register as an Apple Developer and sign up for the WWDC event. This involves paying an annual fee and securing a ticket for the conference, which can be highly competitive.

For the general public, Apple events are typically held digitally, with live streams available on Apple’s website and YouTube. These live streams provide the same content as the in-person event, including product announcements and keynote speeches.
