600 pages of WhatsApp don't prove you have met in the 2 years prior of filling the petition, neither do photographs. They're both considered secondary evidence. If you can, provide copies of boarding passes of the trip you made to be with your fiance. I'm assuming you've only been together once in the previous 2 years?

I believe the G-325 DOES need to have an original signature on it.

If you want to go on a pre-honeymoon, then why not travel directly to South America and then enter the US on the K1 for good?

A similar thread was started just around the same time as this one and someone linked to this thread, about entering the US without activating the K1 visa. The OP of that thread was successful in doing so, but it is a slightly different situation, as they did not marry in that visit.
Just giving you more information, though I maintain that it's still not a good idea to leave the US for your honeymoon.

Several posts violating the TOS removed; Administrative Action taken.

I would take it too. Yes, who knows what can possibly happen to your packet when you keep it. And who knows what can happen to your visa when they keep it.

It's been said time and time again - do not book anything until you have the visa in hand. Sorry about your situation. And it looks like it's another waiting period for you. Hoping it goes by quickly and it turns out to be nothing!

Jenni-- you are on the wrong page. This is what happens in a London case
1) USCIS approves and passes your case off to the Dept of State, which is the "parent" of NVC and the embassy. At that point USCIS is done. Your case will go to NVC first.
2) NVC assigns a new Dept of State case number. Yours will start with LND for London. Then they package up your file and any others going to London and send it off with DHL With luck it is only at NVC for 3 days. Transit takes about 4 days.
3) The DHL box arrives in London. They don't open it the first day. Yes it does go from the delivery site to the Immigrant Visa Unit. When they get around to it (could be 2 weeks) they will notify the beneficiary by mail that they have received the approved petition and invite you to apply for the visa. That letter is the further instruction promised you. They don't send you forms or write out much instruction, but getting the letter means you may begin the next part because they have your file set up. The letter tells you to get your K1 instructions and forms here. http://london.usembassy.gov/iv_15.html. Don't use a phone or tablet because it automatically gives you the mobile version. It's not very good. I know the website extremely well and I can't navigate it or find things on my iPad. Looks like what you copied above might be mobile version.
Nobody is bullsh1tting you. You were told you would get further instruction. YOU WILL. You have to allow time to receive that letter of instruction. It doesn't happen instantly. There's a lot of people waiting to be served. I told you how to contact NVC so you know if it has made the pit stop there yet.
The process you found above is for immigrant visas like spouse visas. You don't do a DS-260 and you don't submit anything until London says so by sending a letter. But you can start learning the K1 process by reading the London K1 instructions. You will submit two online forms and have a medical.
Instructions http://london.usembassy.gov/iv_15.html
4) Once your two online forms and medical results are received by the embassy, prepare to wait up to 6 weeks before they mail a letter saying what date to come to an Interview. That's how it rolls in London.
Getting angry is wasted energy. Immigration is a slow process.

I assume from your post that by being back, you mean, you're back in your own country, correct?
The rules of the K1 visa are very clear, it's valid for a one time only entry in the US and you have to marry the original petitioner within 90 days of your entry in the US. Because you have left the US without complying with these, you have lost what you had gained with your K1 visa. It is no longer valid. If you want to return to the US, you will either have to apply for a new K1 visa, starting the process with a new I-129F petition with USCIS. You can also marry and apply for a spousal visa. Either way, the visa you had is no longer valid and you have to start a new process all over again.

good luck

A parent or someone else who can help you might be a good first stop as opposed to a lawyer.
Even your fiance can help, he can just ask you the information that he needs for the forms, fill them out electronically, and then send them through email when done for you to submit.

That can only happen if it is re-issued and they marry within the original 90 days of their first US entry >
9 FAM 41.81 N6.3 Reissuance of K-1 Visa
(CT:VISA-1547; 09-27-2010)
If a K-1 visa, valid for a single entry and a 6-month period, has already been used for admission into the United States and the alien fiancé(e) has returned abroad prior to the marriage, the consular officer may issue a new K visa, provided that the period of validity does not exceed the 90th day after the date of initial admission of the alien on the original K visa, provided the alien fiancé(e) pays a new application processing fee, and provided also that the petitioner and beneficiary still intend and are free to marry. The alien’s return to the United States and marriage to the petitioner must take place within 90 days from the date of the original admission into the United States in K status.

The Embassy doesn't care (and doesn't need to know) what your uncle promised you - it's completely irrelevant to the process. Have him fill out the I-134 (along with your fiancee) and provide all the supporting documents.

We're on the East Coast too, Georgia.
Our packet is scheduled to be delivered today. I keep checking the tracking number on the USPS website.

Right, all that really matters is if their income is enough to factor in their own household plus the intending immigrants they are sponsoring.

That is what they call visa fraud. She is not able to adjust status while there on a K1 visa. They can get married and file for a CR-1 visa, however she would still need to leave the US prior to the expiration of the tourist visa.
Advising her that they can adjust her status while she is there, and claiming any lawyer would tell them to do that, is not only going against the legislation which clearly states it is not allowed, but also irresponsible on your behalf.
