Visa Help!!!!!!!!!!!!!!!!!!

Hi, folks,

I am trying to invite my parents to attend my graduation ceremony on Dec 20. I have made appointment for them, but they can apply for visa on Dec 22 in Beijing.

I am very eager to let them come. Is there any way I can deal with the problem????? Try to go to Shanghai, or I can buy some numbers in beijing. Is it possible?

Any ideas will be highly appreciated!!!!!!!
Thanks again
