Online meeting is not a real meet and that does not meet the requirements from USCIS. You need to meet in person at least once in the last two years before applying. 

Give it a few visits, see how it goes.

Consulates are staffed by officers trained with some knowledge of the local culture at their post. They have discretion if they spot questionable evidence or anything else that stands out. CO are human too, but the burden is on the applicant to make their case beyond a reasonable doubt.
For an applicant with a genuine case backed up by supporting evidence, terms such as 'fraud' or 'denial' do not usually enter the lexicon. And maybe it's just me, but why refer to your spouse as "an American" versus a more personal "she is American"? Maybe I'm just splitting hair.. Just my 2 cents...

It's not about the sincerity of a wedding. But the culture. And if you are coming from a culture where parent approval is very important and someone says My parents don't even know I am married. That is major. That's why the parents were involved.
Same situation as the OP's a friend of mine has at the USCIS level they requested an affidavit from his parents in Nigeria why they weren't at their wedding (she made mention parents weren't there). Well they weren't there because like the OP they didn't tell the parents because of her older age to their son.
They haven't had interview so we will see what will happen. But at least they got affidavits upfront. But OP's dad changed mine and said we know nothing so it makes it look like "did dad even sign the affidavits at all. " I think that's the OP's concern about fraud.

Did your father actually sign that affidavit or did you? You seem pretty worried about 'fraud' as if you committed one.
Besides, you are speculating, and talking as if you are certain of a denial. Calm down, son. Sit still and wait for a decision. If they need more stuff from you they will contact you. Only then can you get meaningful and specific input from around here.

There is nothing a congressperson or senator can do to repair this, nothing. Elected officials do not have the power to sway the decision of the CO. The OP got himself into this mess and as far as the CO sees it someone along the way has lied.

Its really a coin toss when it comes to India some people have a lot of evidence and letters from the family (both sides) agreeing with the marriage and still get denied most of you where not here when I had the pleasure of dealing with India
then other couples have very little evidence and have a smooth ride all the way threw ........it depends on the officer and how that person felt about the truth of your situation when you were interviewed......
truthfully your fathers answer on the phone may not mean a thing if you had strong evidence and a interview that went well.
I will add you to my prayers hope everything goes well for you

You can legally visit your spouse during the immigration process..  You must convince the officers at the border that you will return to your country.  Just answer all questions truthfully.

It's the Consular Officer you need to convince, not the members here.

Delayed immigration, in and of itself is not much of a factor. Time spent together in person, IS a big factor and becomes more and more important with each added red flag. The point is to both have a legitimate relationship and then live like you have a bona fide marital relationship, not just marry and wait.
Here's a hint for you. When you start thinking and talking like your concern is how you and your wife can be together, instead of how YOU can get a visa, you'll be on a meaningful track.

All three of the above are big red flags. The best way to overcome those flags is to spend a significant amount of time actually living together as man and wife. If she's going to come over, spend a week or two, during which you marry on the first visit, then goes home and files a petition with no further visits before the interview, you can be assured of failure. On the other hand, if she comes and spends a few months, you might have a pretty good chance. The combination of the three things above are serious. It's not so much that you cancelled an interview. The issue there is that you have pursued two separate relationships in a short time, with the intention of US Immigration. That and combined with the other two fits the classic immigration fraud scenario.

I think you are not listening what people tell you. TAKE THE LOSS AND GET TO KNOW EACH OTHER BEFORE YOU MARRY.

There is no stated number of face days needed, by law you could meet at an airport between flights and petition.  The break over point in high fraud countries seems to be about 30 days.  I guess they figure at that point you will know if they snore, fart , pick their nose or have any other deal breaking habits and that you have had enough face time to detect if they are running more than one woman through the lets get married treatment (  I was amazed at a young man I saw in Lagos who had at least 6 different phones and while I was eating got calls twice obviously telling the other party how much they were "the one" )

Next red flag. You will not get a visa if you marry. Not even a K1 with 1 visit.
Increase your time together drastically for own security and visa purposes, and once you are sure he is not only in for a visa, and you have spent plenty of time together e.g. at least 6 months face time, you may think of getting married. Anything else is just insanely risky. There are a "trillion" of cases that are exactly as your case and many ended up with the USC utterly hurt. 
Take care and make sure you see things in an objective way.

Is he 20 years younger than you? Have seen a trillion Ghana/Nigarian/North Africa cases like that. Most of them did not end well for the USC.

Thank you guys for the advice!

Well if you think a skype meeting won't go well then don't do it.  It's probably way too soon anyway.  It is possible your mother is too set in her ways to change or accept.   This will take time.  I wish you the best!

It is imperative your fiance visits and consider more than one visit before filing.  I suggest you work on sharing your fiances good points, strengths, and reason why you love her with your mother.  Endear her to her.  If she learns good things about her she may come around.  Share her likes her interests, her hobbies with your mother.  Think of things they may possibly have in common.  I highly suggest you stress to your fiance to learn about Indian culture, Indian life and customs that will help endear her to your mother and not offend.  Maybe she already has done this but if not she should.  Forgot about bringing your Dad into this right now.  It doesn't sound like a good idea.  DO they skype?  If not, introduce them there.  Let your mother see how much you both care for each other.  Don't continue to repeat the "i'm grown I can do what I want".  That only pushes her away.  You've made your point now move onto helping them learn about each other.  

there was a recent post from India husband and i hope he responds as he wrote
" i walked into interview and the man said we know how to deal with people like you" because of the divorce
you are right and stongly i suggest you are able to prove to your mom this woman is right for you
why not have her come to India and allow them to meet?  works or does't but you will be asked if family approves of this relaitonship
ordinarily i would say marry but maybe K1 and financee visa as a marriage would be a burden if CO denies

As you have already realized your family's approval will be an issue that is best resolved before going onto the visa application process.  Only you and your fiance can determine what works best for your unique situation.  Nothing will give you 100% guarantee of an approval.    You will need strong relationship evidence.  And from the sounds of it alot more facetime.  Skype isn't going to do it.  You need in person visits.
