well one of my questions still remain -
i am US citizen and wife is Perm resident thru our marriage - can either one of us sponsor even though i m not related to my wife's parents directly? if so, are there different documnets requirements for US citizen sponsoring vs. Perm. resident sponsoring?

1) Visitors visas are not a sponsored visa like immigrants. The intending visitor just fills out a DS-156 online prints it out and pays the $131 equivalent fee to the consulate. You can provide an affidavit of support. (I-134) and attach financial evidence.
2) Parents fill out DS-156 on line, print it out and file it to the consulate. And as above you can provide an I-134, and perhaps an invitation letter.
