Soon To Be Mrs. T

It is most likely not a problem. There are other people with a larger age gap.

Be sure to also file a proper change of address with USPS.
REF: https://www.uscis.gov/addresschange
 

I called yesterday to confirm an address change. They were nice and helpful. I called around 9AM EST and waited about a half hour for someone. 

I would try the online thing first, and if didn't work I would call.
 
I called them a couple times in the past, there were helpful, They didn't have the online chat thing back when I contacted them.

If there is an USCIS close to your fiance he can do an infopass and talk to someone in person, of course there is calling or emailing.   Lots of options.   
 
There is also an online contact service, there is even a section for IF you did not receive a notice in the mail:  https://egov.uscis.gov/e-request/Intro.do

Thank you for the reminder @Greenbaum! It is appreciated!
 
Unfortunately, I can't change my Display Name anymore. I hope the "Soon To Be" is enough of an explanation.
 
I have read about the denials because of looking "too married". I'm happy to have known this before our engagement; because of this, we had a simple dinner instead of an engagement party.
 
By the way, what do you think of this RFE? Isn't it kind of contradictory?

We are still waiting for the NOA1 Letter.

That does not apply to the U.S. Embassy in Manila.

I would do it this way:

I'm not sure if the U.S. Embassy or Consulate where you or your fiancé(e) will be interviewing at does but I have been able to schedule a visa interview over the phone.
 
By the way, as far as I know, the validity of your I-129F will be extended if there are no available interview dates before it expires.

I'm guessing that you are trying to schedule your or your fiancé(e)'s K-1 Visa Interview. You can either wait the 72 hours out or call the U.S. Embassy or Consulate where you or your fiancé(e) will be interviewing at and ask them to schedule your interview over the phone.

The information on the website of the U.S. Embassy in Lebanon is different from the usual K-1 process. I think that it would be better if you or your fiancé(e) contacted the U.S. Embassy in Lebanon.
 
Perhaps there are more pertinent information in the regional forum:

I received mine two days after the interview. This was last June.
 
I don't think it is possible to expedite the process but when I was at the U.S. Embassy, those who were approved, myself included, were told that the turnaround time was five days.

The I-134, Affidavit of Support, is for the K-1 Visa Interview at the U.S. Embassy. You send it to your fiancé not to the USCIS.
 
I think that you are confusing the I-134 with the I-864, Affidavit of Support Under Section 213A of the INA. The I-864 is sent to the USCIS but that is for the Adjustment of Status (AOS).
