I read the embassy review and it seems most of them only had good things to say about their interview experience. Since your medical exam will arrive before the interview, then you should have everything you need. You being unemployed (as the beneficiary) doesn't matter. If your petitioner's salary meets the poverty guideline, then you have nothing to worry about.
Just go over your checklist, make sure you don't forget any document (over-prepare if you must), be there on time, and just smile. I know its nerve-racking, but they are only asking questions you already know the answer to. So its like taking a test with the answers written on the board. Just stay calm, don't think too much, and be confident.

The procedure and experience varies widely depending on the embassy and the country in which you are interviewed. My suggestion to you is to go to the embassy reviews section at the top of the page and select the Buenos Aires consulate and see what others have to say about their experiences.
Wishing you all the very best

I had my K1 visa interview in November last year and I was pretty stressed before it even though my then-fiance/now-husband didn't have any red flags in our relationship whatsoever. The interview lasted 5 mins, it was easy, the consul was friendy and I was approved on spot. 2 days later I received my passport with my visa in it, and 11 days after the interview I moved to the US. It was the best feeling in the world to jump into my love's arms knowing we won't have to be apart ever again!
My advice is to triple check everything when putting your paperwork together for the interview. On your interview day, arrive early, relax, smile and answer all the questions truthfully.
Also, as the poster above me suggested, read the appropriate US Embassy/Consulate reviews: http://www.visajourney.com/reviews/index.php?cty=&cnty=Argentina
Bets of luck to you and keep us updated!

Congrates!!!!!
but what's all the visa business got to do with god?!!!
get real
Peace

No offence I don't believe there is a god I went through all the hard work I had to pay for everything I had to work long hard hours

Congratulations che! Me and my fiance have been dating for 4 years as well and we applied for a fiance k-1 in May, I've been to the U.S. a lot of times and you'll love it (she's lived here in Guate with me as well). We're planning on joining the military I move up and get the GC to get a solid foundation for our marriage.
So, if you have any questions, don't doubt on asking, we're all in the same boat, so feel free to ask!
Te cuidas,
Adrian

I agree with Marco&Bettina You should have no problems visa-wise not visiting the US, but I am sure it would help you both if you visited the US before moving. I know it isn't always possible, but if you can make it happen, I would try. If you can't make a visit happen, then try not to worry about it and think of it as an exciting adventure (Getting married and moving to a new country!) and keep an open mind about things.
Good luck!

It will not raise red flags. However, you shouldn't just assume you will like it there. I recommend a visit.

No, there is no red flags about never being in the US before. You should be just fine. Make sure you read the guide on Visa Journey and ask questions if you do not understand the whole process. People here are will gladly to help your immigration process. Good luck!

Yes she can send away the paperwork while she is visiting you. The mailing costs might be rather expensive though and it might be easier to wait or send it now.
I suggest she finds a joint sponsor to help her with the I-134 and then either get a good job or the same sponsor for the I-864 when you AOS after marriage.

If she can find someone to joint-sponsor with her for the I-134 (and subsequent I-864 for AoS) then you could file ASAP.
If you're waiting for her to get a job before you file, it may be more than May 2014 until she has one. At which point, you may want to wait until you know more about her job/salary and whether it's going to be after your 2 years of meeting last, and plan another trip accordingly.
Or, you file the I-129f in May 2014, and hope that she has a job by the time your interview comes around a few months later, but negate the need to meet again. The 2 year meeting requirement is for the I-129f petition. If you file that in time, then you find you haven't met for 2 years at the time of your interview, then that's no problem.
She won't need to provide you the I-134 until after your petition is approved, so she'll have a couple of months at least from filing to find a job (but that's risky, so she should find a joint-sponsor who'd be willing to help if she should fail to find appropriate work).

Yes, it is a requirement that you have met in person in the 2 years prior to filing the I-129F petition, so you do need to factor in those dates. You can always plan another trip between now and when she finishes school, and that will take care of that. As for the money issue, does she have student income? That could be one way to get around it. The other way is for her to find a co-sponsor as many Embassies will accept that. The co-sponsor will have to make above the poverty guideline for their own household plus you.
There are ways to get around the money issue, if that's your only problem, it's not the biggest deal. You having met in person is much more important, as if you don't meet that requirement, the petition will be denied.
