As an Undergraduate student can Join at conference with Full research paper?
I assume you have discussed this with your advisor and figured a way to pay for the airfare before you submitted an abstract to the conference. What makes you think this is a good conference?

I have no idea if this is a valid conference or not.  Perhaps another answer will tell you.  Have you already paid the registration fee?  If not, please wait.  There are conferences out there that just want your registration fee, and make a nice excuse for a vacation.
