Amresh,
Sorry for any confusion, but I was suggesting exactly what Kimberly had also stated that you should contact PMI yourself and ask them how you should state your credentials on the PMP application. I think you should be able to just email PMI and explain your credentials and they should be able to guide you in the proper direction. You might even try their "chat" feature on their website which I successfully used a few days ago. That probably depends on your location and time zone though.
Again, sorry for any misunderstanding. Please post a reply to this and let us know what PMI tells you.
Thanks,
Mark
