It should be noted that the OP has no immigration knowledge at the outset of the thread and probably little if any understanding of international travel. He's learning fast. He now realizes that "don't ask, don't tell" is not applicable because they DO ask.
His fiancee entered the USA illegally (without inspection) and is both ineligible to adjust status or obtain a spouse or fiancee visa AND is subject to a ten year ban on re-entering the USA. He can file for a waiver of that ban but there is far from any assurance that waiver will be granted. It's a lot to deal with in one day.
We have a whole separate forum dealing with waivers but essentially, to be successful, one must show a severe hardship to the US Citizen resulting from their loved one being denied the immigration benefit sought. Separation from a loved one, in and of itself is considered a "hardship" not a "severe hardship".
The OP needs to understand as well that "legal residence" and "citizenship" are entirely different animals and he will not obtain Honduran citizenship in six months. I think he was referring to filing a petition for spouse from Honduras which would require he live there six months, not that he become a citizen of Honduras.
Whether one considers it unfortunate or not, what millions people in similar situations do is simply go on with their lives as illegal aliens indefinitely in the hope some new law including some sort of amnesty will obviate the need to leave the USA indefinitely.

Your statements above conflict. They would know because you were both truthful in filling out the necessary forms to begin the process. Only if you lie would there need to be any other way for them to know. The forms ask where she's been the last five years. To leave the USA any by air or sea, she'll need a valid passport, so there will be a record of her leaving unless she travels overland illegally entering both Mexico and Guatemala before presenting herself at the border of Honduras, essentially retracing the steps of her illegal entries to Guatemala, Mexico and the USA.
Your question itself indicates you contemplate illegal activity.
The legal way is to file the papers truthfully, have her obtain a Honduran passport through a Honduran Consulate in the USA (unless she already has one) and then at the appropriate time she goes home an takes her medicine with the understanding she may never be allowed to return.

Some of us know about things because we've studied them. When others make assertions as if they know, it's best not to presume they don't know what they're talking about. If somebody appears to know something you don't know, there's a pretty good chance they actually DO know something you don't know.
If you read here for a while you'll see all kinds of incorrect advise given by immigration attorneys getting corrected by members here who "know" but aren't attorneys. Nobody has a corner on knowledge, regardless of the subject matter.
While only an attorney can give "legal advice", that term was not in your original assertion.

Just what are YOUR qualifications to make assertions about the extent of the knowledge others have? Please speak for yourself and your own abilities, not those of others about which you know nothing.

You're mixing contexts. First, "secondary" does not equal "not important". The context in which photos in general are "secondary evidence" is when used as evidence of meeting in person and as such are not sufficient without "primary evidence" to go with them.
In the context of evidence of a bona fide relationship, photos are secondary to the interview and secondary to the evidence of time spent together but they ARE important.
I suspect that in the case of the OP, the interview didn't go well and that the photos provided were not helpful in determining the bona fides of the relationship. People often get confused about the meaning of "bona fide" and concentrate on showing they are legally married, rather than focusing on the "relationship". Similar issues come up in fiancee cases, where to much focus is given to evidence of meeting instead of separating the issue of meeting from the issue of having a bona fide "relationship".

The I-864 has limited impact, period. Within that limited impact, a prenup will not overcome the contractual basis in the I-864. This doesn't mean your prenup has no value for the myriad of issues not addressed in the I-864. You'll better understand if you read the I-864.

Many of us had no immigration experience and many had little international travel experience before becoming engaged or married to foreigners. The question indicates such lack of experience as well as some confusion. Passports are issued by the country of citizenship and visas are affixed to passports. A K1 visa holder is more than three years from any potential of being a US Citizen or having a US passport.
Costa Rica will issue a passport BEFORE any actual application for a visa is filed but no passport is needed at the time of petition filing. The passport is not needed until after the petition is approved but getting it a comfortable amount of time in advance of the interview is a very good idea.

She can marry but not stay and adjust status. That would be fraud.
If she marries on this visit, her 19 year old will have no immigration path in the next several years.
If it is important for the 19 year old to come to the USA, the only available path is the K1 and K2 visa route and that needs to get started as soon as possible or will run out of time too. That means no marriage until after the K1 is in hand and back in the USA.

Good choice. People often forget to consider the possibility of the originating flight departing late, so arriving late. All my extra overnights were the result of late departing outbound flights, not delays in customs or immigration. When there is no later flight to catch, you're stuck. It's only an inconvenience for me but for a foreigner arriving in the USA with little to no English skill, even an overnight paid for by the airline is a major hassle to deal with, not to mention the heartache of the delayed reunion.

My suggestion is that you simply give this thread a rest. You got your answers in the first few posts. If you have other questions later, simply ask them, then ignore any responses that aren't helpful to you.

Just think about how much you're gambling on that assumption. Not only is there a lifetime ban for the alien SO but I believe that DHS can charge the USC criminally in Federal Court with punishment being several years in prison and fines in the tens (if not hundreds) of dollars!
Even if you get away with the lie once, you have to remember it and continue it flawlessly at every step of the process. Even once naturalized if they discover fraud they can revoke everything that was based on the fraudulent statements and shatter whatever life you've built up to that point.

Original signature or you could try just sending without a signature and entering "will sign at Consulate if needed".

Those would be the I-129F instructions you surely downloaded and carefully studied prior to completing the petition. If you have not already done so, please do. There's no telling what other critical factors you missed until you do.

It's probably best to marry but not because it's cheaper. Consider the cost of travel to get married as part of the cost.
The "issues" are that his visa will be denied because he was here illegally. He'll be subject to a ten year ban on re-entering the USA. You can file a waiver request after the denial but would need to show evidence of a severe hardship to you the US Citizen to be successful. Missing your spouse is not considered a severe hardship. We have a whole forum here discussing waivers so check that out before you make any decisions.

Generally, they just deal with the document they asked for. They may have a few more questions. In most Consulates, you would only submit the documents without speaking to an actual Consular Officer but in Lagos, it's more common to have a second interview when the document(s) are submitted.

This should be making you wonder what other I-130 instructions you failed to carefully study. Do it now, so you can be prepared. Also study the guides and the wiki for the NVC shortcuts or you'll wish you had. (In addition to feeling silly for not having done so.)
