According to the embassy, in a conversation I had with an official there via email, the biggest reason was what I mentioned related to her being an immigrant here. He literally told me that she was considered a high-risk person because she immigrated to Argentina from a poor country. There was not much more information related to his comment about that.
He also said that marriage does mean anything. Everyone applying for a visa must stand on his or her own, marriage is, if anything, a detriment to a tourist visa, going back to the first comment.
In addition, he wrote that a person needs to prove roots in the country in which they are resident. Usually this means a job, paying taxes, a bank account, owning a car, owning property, a large family, etc. They want to know that the person will return to their country of origin within the parameters of the visa.
My wife held jobs in the black here the first year or so that she lived here, until she met me. She was very unsophisticated about things like opening a bank account and such. Once we got married, she stopped working.
Now, she has a bank account in her name and she does some work, part time, in the black again (she likes to be independent and not feel like she's spending "our" money on herself - I love the attitude, but it was her idea
![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
). We're working on getting her enrolled as a monotributista so she can prove salary and tax payments.
She owns no cars, no property. Her extended family with the actual roots are still in Paraguay, where she is not resident.
I was told by the embassy before she went to her interview that I would not be allowed to accompany her into the interview, even though I had read many forums talking about exactly that be allowed. In my place, I wrote a letter explaining that she was married to me, that we wanted to visit my folks due to their age and condition. I included my bank statements, her banks statements (at the time only about a year and a half of history), our marriage certificate from Paraguay (we've been married for almost five years now, not doing this just to get her a tourist visa), nicely legalized (which I had also registered with the US Paraguayan embassy shortly after we were married), my birth certificate, her birth certificate, our past 4 years of long-term rental contracts, the last 4 years of payments to private schools for her sister (trying to prove commitment to be here), made clear in my letter my business arrangements and showed contracts I had with various contract programmers here, all to prove I had no intent to return to the US permanently any time soon. I think there was more even, but don't recall it all now.
Problem is, most of the important stuff was in my name and not hers. We never considered she would need such a history to get a visa.
This was at the beginning of the year that she was rejected. We are going to try again, in addition to all the other stuff, this time with a notarized letter from my folks asking her to be allowed to come, with some of their medical reports/bills, etc. I'm also going to go with her this time (she didn't want me to go last time - she wanted to do it on her own since they weren't going to let me in - I think that was a mistake on my part the first time) in the hopes that I can have some influence as a citizen, in some manner.
I wonder sometimes if the root of the problem was just that our age difference is significant and they plain didn't believe her - maybe thought the letter, marriage certificate and other things were forgeries or something, that we got divorced shortly after, I don't know.
The officials at the embassy have the discretion as to whether or not to give a visa. My wife told me the official with whom she sat down was very sympathetic, but said she had to ask her supervisor. My wife watched her talk to the supervisor, show the documents we had, and without even reviewing the documents or saying a word to the official conducting the interview, simply shook her head "no" and dismissed the interviewing official.
My poor wife felt humiliated. She cried off and on for days after, and until the last couple of weeks had refused to even try again.
