Interview after submitting I-601 and I-212

[Json 2]

My husband and I completed our I601 waiver and I212 application independently.  We submitted both documents on March 20th.  Yesterday May 2nd, I received a voicemail from the attorney's office we used in years past.  The message stated that the US consulate had been trying to reach my husband to schedule an interview and they stated the interview would be at the end of the month!!!!!!   We have yet to receive an approval letter/package )which is what I read other people receive) by way of DHL.  My first question: is it safe to say we are approved since the interview was scheduled?  My husband went to the embassy to see if they would tell him more information since we didn't get a letter.  Security would not let him enter and advised that he just show up for the interview.  So he is going into the interview blind.  My second question is: are there any standard documents that he should take or actions that he should make  prior to this particular interview.  My husband has been out of the country since October 2013, don't want to mess this up or prolong it.  Any advice would be greatly appreciated.

I would have back up prroofs of what they already have, they lose stuff ar rimes, there

can be final questions to be asked, please have him go over all he had said before,

and I'd have some proof that I'd stayed out of the US during this period with paystubs

medical records (if any. lease etc) and finally affer waiver approvals they do a mini

interview again if a long time has ran off also have medical redone. Try emailing

them to see if they will require anything else
