USA, Canada / Getting a VISA to USA by a Polish person nowadays [339]

I have so many questions about getting a tourist visa for my fiancee. I am hoping i could get some insight.

Details:

Single Mother of 2
Age 38
owns her own flat
owns her own car
Children are good students
All of her family is in Poland
Has money in the bank
Lived at the same address 5 years
Has traveled outside of Poland (with and without me)
No job, a stay at home Mom.

She was denied a tourist visa last September. She was really not allowed to speak at her interview. She was simply told, NO JOB, no visa. She was not allowed to present the evidence that she brought (e.g. deed to her flat, childrens' birth certificates etc)

I am returning to Poland April 10 through 18 and will go with her to Warsaw to try again.

On the Warsaw website, there is a page that says that I can write a letter... but I do not have to come to the Embassy. But no place can I find if I can go with her for her interview, so that is my 1st question... can I?

I will have her bring all the evidence again. I have my Congressman writing a letter to the Embassy requesting that the Embassy give her every consideration under the law. Which is the best my Congressman can do, since the Embassy and the CO that does the interview are basically GODS when it comes to their decision.

I have filed for a K1 Visa so I will bring a copy of that file as evidence that we are going about this move to the US in a legal manner. She will disclose that her Fiancee live in and is a US citizen on her DS-156.

I have advised her to be a little more forceful in her interview to try to get the CO to look at evidence and maybe even ask to see a supervisor if necessary.

Have I missed anything? Any advice on how to be more successful? Any insights?

As an aside... just a little rant on my part... It really frosts my bottom to know that these decisions do not seem to be based on fact... much more subjective (in my opinion) than they should be.

Thanks in advance people :)
