Emergency AP does exist....but a wedding not normally classified as an emergency....an emergency is kin to a crisis...........maybe suggest a Facebook live wedding.

The wedding is not a reason for emergency parole. If he sends out emergency parole application and put "wedding" as a reason.. USCIS will laugh at him. 
 

Oh is not quite the end of the world,we judge you not foryour  limited facetime in the last 11 yrs because we are not in your relationship and dont know the story which apears to be 11 yrs long.
Sometimes longer can be better,i see too many cases where people know each for 6 months with lots of facetime and file for visa but the final story is not the one your read called "Cinderella"
 
Sometime the slow walk over the rainbow ends with you finding a pot of gold! Just keep your faith......

What evidence of the relationship did you provide, though? If all that was stated was the time you dated or number of visits, then that would be a high concern for fraud, hence why they are asking for some documented evidence of the relationship.
 
A 221g pending additional documents means they don't have enough information to determine eligibility for the visa yet. Once they receive the additional documents, they will review them and make a decision (or request more documents, if needed). it does not mean they intend to refuse the visa.
That said, a refused visa does go through AP while the case is reviewed, and potentially prepared to have the petition sent back to USCIS. But it sounds like they only asked for more documents because they were not provided at the time of the interview.

Normally two weeks if there are no additional problems. Need just a little more patience. Don't buy an airline ticket till you have the passport with visa in hand.

it  depends on the CO. Some will ask lots of proof, some dont.  In my case I was not asked but I brought bunch of email, viber, fb messenger conversation just in case they will ask.  my friend was asked those proof of  conversation luckily she brought some.
