How to face second interview

[clamasl]

Hi,

My girlfriend is from Brazil and she attempted to get a visitor's visa back in July. I was in Brazil with her when we filled out the form DS-156 in which she put that she was going to stay with me. In her first attempt when she was asked who I was she answered that I was her boyfriend, and the consular officer without saying anything else, deny her the visitor visa. I know I read that you cannot say that to a consular officer but unfortunately we had already filled out DS-156 online. Now the thing is this I am actaully wating for my interview to become a US citizen and after that I will apply to get here in the states as a K1 fiance visa and I didn't want her to lie the first time. Eventually, I will get here even if they deny fer visitor's visa.
Since I wanted her to come here and visit me(because I have no vacation left), I asked her to apply again, and she has a second interview at the end of october.
Even though she has a very slim chance to get her visitor's visa I would like to ask the gurus how do you guys think would be the best approach this time. I don't want her to lie because in the future she could have problems when she goes and apply for the K1.

Any advice would be greatly appreciated.
Thanks!!

Your girlfriend needs to show proof of strong ties to her country. More than proving that she has a place to stay and someone to cover her expenses in the US. Look at the B-2 visitor section of the website and that will help you two some.

If asked I would say I am going to visit my friend and sighseeing. But the most important is to show proof of ties to Brazil.
