K1/CR1 inquiring

Even if you find this reason out, your petition will not be reviewed again.
Only IR/CR 's which are the spousal visas get reviewed by USCIS once returned from the embassy, never K1's anymore, though they used to
a decade ago. Any USCIS who tells you you get a review if you know the reason of the returned K1 is simply misinforming you.
First contact a senator to inquire the reason for refusal and go from there, you are less likely to get one personally if you email them but you
can try. You can also submit a specific FOIA request to the embassy which unfortunately can take many months.(Form online). 
Best wishes for a successful outcome with your next petition.

 

Good, because everyone here is trying there best to give you the proper advice, but this advice cannot come inside a vacuum.  You have a very complicated situation that will need some incredible amount of sorting out before you should proceed down any chosen path.  I dislike attorneys because for the most part they aren't necessarily helpful but I think this is a different.  So at some point an incredibly savvy and experienced immigration attorney might be wise choice if you choose to motor ahead

I don't think there is any question as to what the issue is.  It has got to be the validity of the relationship when you consider all the noise going on around him

Understand, however, in many cases, Immigration is about opinions unfortunately. Whether the CO or us giving advice based on our experiences based on law.
 
All too often, (not in your case), people come on board here and leave out either material facts or give information to just support what they think.
 
The truth is The Gambia is a high refugee/fraud country for Visas (I know of three here in NYC). Visa overstays etc....so this is something I am sure the Consular Officer knew and processed your case.
 
Yes the I-129f expires on being returned. On situations such as your fiance, it is best for a CR1, then have many more visits. Very expensive I am afraid but thank goodness it is Europe which at the moment at least has 'less' expensive fares than in the past

Thanks!  I spoke with an Officer yesterday.  He said that when they close a file because of Expiration date, it is not a "denial" but there was an "issue".  Since it is closed, they will not review it and we can refile like you said.  The thing is, like you said, we need to find out what "issue" got it sent back to be reviewed again. I will have a long talk with him and we will try to figure this out.

So it sounds like the K1 was denied, petition sent back to USCIS to expire.  As others have said, you can re-file the I129F after correcting the issues that resulted in the first refusal (sounds like a long talk is needed with your fiancé), or you can meet up somewhere and get married then file for a spousal visa.
 
Good Luck! 

Gambia and Italy (Europe). Google refugees....tons of information. Gambians are desperate to leave their country. I am sure the US Embassy knew this.
 
How old is your fiance? How old are you?
What is his status in Italy (Europe)>
The Gambia as a high muslim population. What is your religion?
(Speaking as an African). Marriage is very important to the culture. The CO might be wondering why you did not get married in The Gambia. 
 
You provide very little information, yet seem to expect posters to provide an opinion.

The petition will not be reviewed even though your update stated it would.
 
You have to start over. Try to find out the reason why the visa was refused. Could be just the general ' not bona fide' finding.
Overcome the reason and convince them that you are a genuine couple if you want to pursue another petition.
I suggest marrying in his country and take lots of photos with all of his family. I would forget the fiance visa and do the CR1
after marrying there.
You can try your senator to make an inquiry as to the reason for refusal. A senator can not do a thing to get it reviewed so don't even
confuse them with that kind of request, just tell them to find out the reason(s) plain and simple.
If he is not legally residing in Italy then that's another reason for refusal, what visa made it possible for him to go to Italy ?
If it was a student visa is he still studying there and is it still valid ? Did he overstay on a B2 there ? 
Did he fill out a previous visa application for a US visa and is the data entered the same as for the K1 ?
Did someone else petition him before ?
You need to have a detailed conversation with him and ask what the CO was dwelling on at the interview, what was asked, perhaps several 
times.

In FY 2016, Gambia had a 69.9% refusal rate for B visas.  

Hey
I don't have any idea how can I explain my situation,
My relationship with my wife starts in 2013 , we met each other on Facebook as many other couples. After many chats and corresponds , we discovered that we honestly fall in love with each other and we want to spend the rest of of our life together because we simply have many things in common. My wife decided to give me a first visa in January, she spent with me and my family ten days even though she wants to stay more days but she has to come back to her kids and job as well. My wife is 2 years than me.
We firstly applied for tourist visa in March 2014, the officer told me that you're denied because you may not come back to morocco as you don't have any properties.
After six months , we decided to apply for k1 visa . We prepared everything and send them our package. My interview was scheduled last March 19th 2015. I went to AP for 6 months. My wife tries to contact with the consulate to know what's going there since they didn't ask me for more evidence. She contacted with general inspectors , her doctor and a congressman.
After a long time , I got a called from the consulate saying that I should be in the consulate 10am, 31 August. I went there yesterday. I was waiting and waiting until the officer called on me . He didn't talk with me much , he only handed me a paper marked " section 221g which prohibits the issuance of a visa to anyone whose applications doesn't comply with the provisions of the immigration and nationality Act or regulations issued pursuant thereto. The following remarks apply in your case : Returned to USCIS for reconsideration "
I am asking you if there someone who has experienced this situation before , I want your help please. Is there any possibility to make them not to send it back to USCIS .
Thx u in advance

Yes, very hard. we got our case # last Oct 2nd. Until now it's still there. I hope we will have good news next week. Happy for you

Hello everybody, after 8 weeks at nvc in administrative processing, finally they sent the case to the embassy, my status says now in transit.
I hope next week hear something from embassy.
I wish everybody here get your cases send to embassy

Great news! Hope things go smoothly from here on 

So our case managed to get out of the NVC on Friday, September 29th after being stuck for 1 month and 1 week. We've managed to reach supervisor calling on Friday and complained about passed 30 days (according to what is written on NOA2 letter). Maybe that call worked, who knows, we've even heard apologies from supervisor for such a delay. 
Just leaving it here for the following couples. If you are in the same situation - wait for 30 days to pass, call NVC and ask for supervisor. Apparently this can help somehow. 
Wish everyone all the best it this process and happily ever after with the loved ones.
