waiting on NOA2- what needs to be gathered?

[bekam 0]

hi,

i sent i-129f packet (Aug 14, 2011) got NOA1/ text message/mail- (Aug 17,2011).

and now im waiting. ...

I was just wondering if there were things that I should start gathering right now. i know there is a lot of waiting left, and I do have time, but i just wanted to know

-should i start getting everything for the 1-134 (affidavit of support)- my parents are going to co-sponsor. should they start getting papers together?

-also, (my fiance is in mexico) - what is the packet 3 (that they send him, right?) actually going to have in it? it's the D-???? and some more D-???

.. i was thinking we could go ahead and be prepared and know what he was going to have to fill out.

-also, anyone with fiance in mexico- how long did process take?? ( from noa1-noa2-packet 3-interview-visa)...

-am i right that there are no vaccine requirements with mexico?

anyone with specific advice with packet 3 for mexico- would be appreciated!

yall have been awesome answering questions in the past, and ive been reading from here for months and months now.. please help me out if you can
