A pagal again you dont need anyone to sponser u b1 b2 . People get invitation for confrence in google, who , unhcr , and still cant secure b1 visa . Invitation and sponsorship  are two entirely seperate words dnt mix them up .
There is nothing called sponsorship in b1 b2 visa if you mean invitation thats another story but sponsorship and invitstion are entirely different words ( repeating 4 ubagain)

Prachanda will never use regular pasport for his life because he is ex prime minister . He has that privilege.

You dont need to be sorry for anything kids make mistake thats OK .
